+// The raw monitor subsystem is entirely distinct from normal
+// java-synchronization or jni-synchronization. raw monitors are not
+// associated with objects. They can be implemented in any manner
+// that makes sense. The original implementors decided to piggy-back
+// the raw-monitor implementation on the existing Java objectMonitor mechanism.
+// This flaw needs to fixed. We should reimplement raw monitors as sui-generis.
+// Specifically, we should not implement raw monitors via java monitors.
+// Time permitting, we should disentangle and deconvolve the two implementations
+// and move the resulting raw monitor implementation over to the JVMTI directories.
+// Ideally, the raw monitor implementation would be built on top of
+// park-unpark and nothing else.
+//
+// raw monitors are used mainly by JVMTI
+// The raw monitor implementation borrows the ObjectMonitor structure,
+// but the operators are degenerate and extremely simple.
+//
+// Mixed use of a single objectMonitor instance -- as both a raw monitor
+// and a normal java monitor -- is not permissible.
+//
+// Note that we use the single RawMonitor_lock to protect queue operations for
+// _all_ raw monitors. This is a scalability impediment, but since raw monitor usage
+// is deprecated and rare, this is not of concern. The RawMonitor_lock can not
+// be held indefinitely. The critical sections must be short and bounded.

+// Theory of operations -- Monitors lists, thread residency, etc:
+//
+// * A thread acquires ownership of a monitor by successfully
+// CAS()ing the _owner field from null to non-null.
+//
+// * Invariant: A thread appears on at most one monitor list --
+// cxq, EntryList or WaitSet -- at any one time.
+//
+// * Contending threads "push" themselves onto the cxq with CAS
+// and then spin/park.
+//
+// * After a contending thread eventually acquires the lock it must
+// dequeue itself from either the EntryList or the cxq.
+//
+// * The exiting thread identifies and unparks an "heir presumptive"
+// tentative successor thread on the EntryList. Critically, the
+// exiting thread doesn't unlink the successor thread from the EntryList.
+// After having been unparked, the wakee will recontend for ownership of
+// the monitor. The successor (wakee) will either acquire the lock or
+// re-park itself.
+//
+// Succession is provided for by a policy of competitive handoff.
+// The exiting thread does _not_ grant or pass ownership to the
+// successor thread. (This is also referred to as "handoff" succession").
+// Instead the exiting thread releases ownership and possibly wakes
+// a successor, so the successor can (re)compete for ownership of the lock.
+// If the EntryList is empty but the cxq is populated the exiting
+// thread will drain the cxq into the EntryList. It does so by
+// by detaching the cxq (installing null with CAS) and folding
+// the threads from the cxq into the EntryList. The EntryList is
+// doubly linked, while the cxq is singly linked because of the
+// CAS-based "push" used to enqueue recently arrived threads (RATs).
+//
+// * Concurrency invariants:
+//
+// -- only the monitor owner may access or mutate the EntryList.
+// The mutex property of the monitor itself protects the EntryList
+// from concurrent interference.
+// -- Only the monitor owner may detach the cxq.
+//
+// * The monitor entry list operations avoid locks, but strictly speaking
+// they're not lock-free. Enter is lock-free, exit is not.
+// See http://j2se.east/~dice/PERSIST/040825-LockFreeQueues.html
+//
+// * The cxq can have multiple concurrent "pushers" but only one concurrent
+// detaching thread. This mechanism is immune from the ABA corruption.
+// More precisely, the CAS-based "push" onto cxq is ABA-oblivious.
+//
+// * Taken together, the cxq and the EntryList constitute or form a
+// single logical queue of threads stalled trying to acquire the lock.
+// We use two distinct lists to improve the odds of a constant-time
+// dequeue operation after acquisition (in the ::enter() epilog) and
+// to reduce heat on the list ends. (c.f. Michael Scott's "2Q" algorithm).
+// A key desideratum is to minimize queue & monitor metadata manipulation
+// that occurs while holding the monitor lock -- that is, we want to
+// minimize monitor lock holds times. Note that even a small amount of
+// fixed spinning will greatly reduce the # of enqueue-dequeue operations
+// on EntryList|cxq. That is, spinning relieves contention on the "inner"
+// locks and monitor metadata.
+//
+// Cxq points to the the set of Recently Arrived Threads attempting entry.
+// Because we push threads onto _cxq with CAS, the RATs must take the form of
+// a singly-linked LIFO. We drain _cxq into EntryList at unlock-time when
+// the unlocking thread notices that EntryList is null but _cxq is != null.
+//
+// The EntryList is ordered by the prevailing queue discipline and
+// can be organized in any convenient fashion, such as a doubly-linked list or
+// a circular doubly-linked list. Critically, we want insert and delete operations
+// to operate in constant-time. If we need a priority queue then something akin
+// to Solaris' sleepq would work nicely. Viz.,
+// http://agg.eng/ws/on10_nightly/source/usr/src/uts/common/os/sleepq.c.
+// Queue discipline is enforced at ::exit() time, when the unlocking thread
+// drains the cxq into the EntryList, and orders or reorders the threads on the
+// EntryList accordingly.
+//
+// Barring "lock barging", this mechanism provides fair cyclic ordering,
+// somewhat similar to an elevator-scan.
+//
+// * The monitor synchronization subsystem avoids the use of native
+// synchronization primitives except for the narrow platform-specific
+// park-unpark abstraction. See the comments in os_solaris.cpp regarding
+// the semantics of park-unpark. Put another way, this monitor implementation
+// depends only on atomic operations and park-unpark. The monitor subsystem
+// manages all RUNNING->BLOCKED and BLOCKED->READY transitions while the
+// underlying OS manages the READY<->RUN transitions.
+//
+// * Waiting threads reside on the WaitSet list -- wait() puts
+// the caller onto the WaitSet.
+//
+// * notify() or notifyAll() simply transfers threads from the WaitSet to
+// either the EntryList or cxq. Subsequent exit() operations will
+// unpark the notifyee. Unparking a notifee in notify() is inefficient -
+// it's likely the notifyee would simply impale itself on the lock held
+// by the notifier.
+//
+// * An interesting alternative is to encode cxq as (List,LockByte) where
+// the LockByte is 0 iff the monitor is owned. _owner is simply an auxiliary
+// variable, like _recursions, in the scheme. The threads or Events that form
+// the list would have to be aligned in 256-byte addresses. A thread would
+// try to acquire the lock or enqueue itself with CAS, but exiting threads
+// could use a 1-0 protocol and simply STB to set the LockByte to 0.
+// Note that is is *not* word-tearing, but it does presume that full-word
+// CAS operations are coherent with intermix with STB operations. That's true
+// on most common processors.

+// ::enter() path, resulting in the entering thread being stranding
+// and a progress-liveness failure. Stranding is extremely rare.
+// We use timers (timed park operations) & periodic polling to detect
+// and recover from stranding. Potentially stranded threads periodically

+// The CAS() in enter provides for safety and exclusion, while the CAS or

+// Adaptive Spinning Support
+//
+// Adaptive spin-then-block - rational spinning
+//
+// Note that we spin "globally" on _owner with a classic SMP-polite TATAS
+// algorithm. On high order SMP systems it would be better to start with
+// a brief global spin and then revert to spinning locally. In the spirit of MCS/CLH,
+// a contending thread could enqueue itself on the cxq and then spin locally
+// on a thread-specific variable such as its ParkEvent._Event flag.
+// That's left as an exercise for the reader. Note that global spinning is
+// not problematic on Niagara, as the L2$ serves the interconnect and has both
+// low latency and massive bandwidth.
+//
+// Broadly, we can fix the spin frequency -- that is, the % of contended lock
+// acquisition attempts where we opt to spin -- at 100% and vary the spin count
+// (duration) or we can fix the count at approximately the duration of
+// a context switch and vary the frequency. Of course we could also
+// vary both satisfying K == Frequency * Duration, where K is adaptive by monitor.
+// See http://j2se.east/~dice/PERSIST/040824-AdaptiveSpinning.html.
+//
+// This implementation varies the duration "D", where D varies with
+// the success rate of recent spin attempts. (D is capped at approximately
+// length of a round-trip context switch). The success rate for recent
+// spin attempts is a good predictor of the success rate of future spin
+// attempts. The mechanism adapts automatically to varying critical
+// section length (lock modality), system load and degree of parallelism.
+// D is maintained per-monitor in _SpinDuration and is initialized
+// optimistically. Spin frequency is fixed at 100%.
+//
+// Note that _SpinDuration is volatile, but we update it without locks
+// or atomics. The code is designed so that _SpinDuration stays within
+// a reasonable range even in the presence of races. The arithmetic
+// operations on _SpinDuration are closed over the domain of legal values,
+// so at worst a race will install and older but still legal value.
+// At the very worst this introduces some apparent non-determinism.
+// We might spin when we shouldn't or vice-versa, but since the spin
+// count are relatively short, even in the worst case, the effect is harmless.
+//
+// Care must be taken that a low "D" value does not become an
+// an absorbing state. Transient spinning failures -- when spinning
+// is overall profitable -- should not cause the system to converge
+// on low "D" values. We want spinning to be stable and predictable
+// and fairly responsive to change and at the same time we don't want
+// it to oscillate, become metastable, be "too" non-deterministic,
+// or converge on or enter undesirable stable absorbing states.
+//
+// We implement a feedback-based control system -- using past behavior
+// to predict future behavior. We face two issues: (a) if the
+// input signal is random then the spin predictor won't provide optimal
+// results, and (b) if the signal frequency is too high then the control
+// system, which has some natural response lag, will "chase" the signal.
+// (b) can arise from multimodal lock hold times. Transient preemption
+// can also result in apparent bimodal lock hold times.
+// Although sub-optimal, neither condition is particularly harmful, as
+// in the worst-case we'll spin when we shouldn't or vice-versa.
+// The maximum spin duration is rather short so the failure modes aren't bad.
+// To be conservative, I've tuned the gain in system to bias toward
+// _not spinning. Relatedly, the system can sometimes enter a mode where it
+// "rings" or oscillates between spinning and not spinning. This happens
+// when spinning is just on the cusp of profitability, however, so the
+// situation is not dire. The state is benign -- there's no need to add
+// hysteresis control to damp the transition rate between spinning and
+// not spinning.

+// ParkEvents are type-stable and immortal.
+//
+// Lifecycle: Once a ParkEvent is associated with a thread that ParkEvent remains
+// associated with the thread for the thread's entire lifetime - the relationship is
+// stable. A thread will be associated at most one ParkEvent. When the thread
+// expires, the ParkEvent moves to the EventFreeList. New threads attempt to allocate from
+// the EventFreeList before creating a new Event. Type-stability frees us from
+// worrying about stale Event or Thread references in the objectMonitor subsystem.
+// (A reference to ParkEvent is always valid, even though the event may no longer be associated
+// with the desired or expected thread. A key aspect of this design is that the callers of
+// park, unpark, etc must tolerate stale references and spurious wakeups).
+//
+// Only the "associated" thread can block (park) on the ParkEvent, although
+// any other thread can unpark a reachable parkevent. Park() is allowed to
+// return spuriously. In fact park-unpark a really just an optimization to
+// avoid unbounded spinning and surrender the CPU to be a polite system citizen.
+// A degenerate albeit "impolite" park-unpark implementation could simply return.
+// See http://blogs.sun.com/dave for more details.
+//
+// Eventually I'd like to eliminate Events and ObjectWaiters, both of which serve as
+// thread proxies, and simply make the THREAD structure type-stable and persistent.
+// Currently, we unpark events associated with threads, but ideally we'd just
+// unpark threads.
+//
+// The base-class, PlatformEvent, is platform-specific while the ParkEvent is
+// platform-independent. PlatformEvent provides park(), unpark(), etc., and
+// is abstract -- that is, a PlatformEvent should never be instantiated except
+// as part of a ParkEvent.
+// Equivalently we could have defined a platform-independent base-class that
+// exported Allocate(), Release(), etc. The platform-specific class would extend
+// that base-class, adding park(), unpark(), etc.
+//
+// A word of caution: The JVM uses 2 very similar constructs:
+// 1. ParkEvent are used for Java-level "monitor" synchronization.
+// 2. Parkers are used by JSR166-JUC park-unpark.

-// * The current implementation of muxAcquire-muxRelease uses its own

-// we could eliminate _MuxEvent and "borrow" _ParkEvent as long

-//
-// * Usage:
-// -- Only as leaf locks
-// -- for short-term locking only as muxAcquire does not perform
-// thread state transitions.
-//
-// Alternatives:
-// * We could implement muxAcquire and muxRelease with MCS or CLH locks
-// but with parking or spin-then-park instead of pure spinning.
-// * Use Taura-Oyama-Yonenzawa locks.
-// * It's possible to construct a 1-0 lock if we encode the lockword as
-// (List,LockByte). Acquire will CAS the full lockword while Release
-// will STB 0 into the LockByte. The 1-0 scheme admits stranding, so
-// acquiring threads use timers (ParkTimed) to detect and recover from
-// the stranding window. Thread/Node structures must be aligned on 256-byte
-// boundaries by using placement-new.
-// * Augment MCS with advisory back-link fields maintained with CAS().
-// Pictorially: LockWord -> T1 <-> T2 <-> T3 <-> ... <-> Tn <-> Owner.
-// The validity of the backlinks must be ratified before we trust the value.
-// If the backlinks are invalid the exiting thread must back-track through the
-// the forward links, which are always trustworthy.
-// * Add a successor indication. The LockWord is currently encoded as
-// (List, LOCKBIT:1). We could also add a SUCCBIT or an explicit _succ variable
-// to provide the usual futile-wakeup optimization.
-// See RTStt for details.
-// * Consider schedctl.sc_nopreempt to cover the critical section.

-// As noted elsewhere, the correct long-term solution is to deflate at

-// by the number of threads. That policy obviates the need for scavenging at
-// STW safepoint time. As an aside, scavenging can be time-consuming when the

-// into much HotSpot code that the object::monitor relationship, once established
-// or observed, will remain stable except over potential safepoints.
-//
-// We can use either a blocking synchronous VM operation or an async VM operation.
-// -- If we use a blocking VM operation :
-// Calls to ScavengeCheck() should be inserted only into 'safe' locations in paths
-// that lead to ::inflate() or ::omAlloc().
-// Even though the safepoint will not directly induce GC, a GC might
-// piggyback on the safepoint operation, so the caller should hold no naked oops.
-// Furthermore, monitor::object relationships are NOT necessarily stable over this call
-// unless the caller has made provisions to "pin" the object to the monitor, say
-// by incrementing the monitor's _count field.
-// -- If we use a non-blocking asynchronous VM operation :
-// the constraints above don't apply. The safepoint will fire in the future
-// at a more convenient time. On the other hand the latency between posting and
-// running the safepoint introduces or admits "slop" or laxity during which the
-// monitor population can climb further above the threshold. The monitor population,
-// however, tends to converge asymptotically over time to a count that's slightly
-// above the target value specified by MonitorBound. That is, we avoid unbounded
-// growth, albeit with some imprecision.
-//
// The current implementation uses asynchronous VM operations.
//
-// Ideally we'd check if (MonitorPopulation > MonitorBound) in omAlloc()
-// immediately before trying to grow the global list via allocation.
-// If the predicate was true then we'd induce a synchronous safepoint, wait
-// for the safepoint to complete, and then again to allocate from the global
-// free list. This approach is much simpler and precise, admitting no "slop".
-// Unfortunately we can't safely safepoint in the midst of omAlloc(), so

-// Note that we spin "globally" on _owner with a classic SMP-polite TATAS

-// a contending thread could enqueue itself on the cxq and then spin locally
-// on a thread-specific variable such as its ParkEvent._Event flag.
-// That's left as an exercise for the reader. Note that global spinning is
-// not problematic on Niagara, as the L2$ serves the interconnect and has both
-// low latency and massive bandwidth.
-//
-// Broadly, we can fix the spin frequency -- that is, the % of contended lock
-// acquisition attempts where we opt to spin -- at 100% and vary the spin count
-// (duration) or we can fix the count at approximately the duration of
-// a context switch and vary the frequency. Of course we could also
-// vary both satisfying K == Frequency * Duration, where K is adaptive by monitor.
-// See http://j2se.east/~dice/PERSIST/040824-AdaptiveSpinning.html.
-//
-// This implementation varies the duration "D", where D varies with
-// the success rate of recent spin attempts. (D is capped at approximately
-// length of a round-trip context switch). The success rate for recent
-// spin attempts is a good predictor of the success rate of future spin
-// attempts. The mechanism adapts automatically to varying critical
-// section length (lock modality), system load and degree of parallelism.
-// D is maintained per-monitor in _SpinDuration and is initialized
-// optimistically. Spin frequency is fixed at 100%.
-//
-// Note that _SpinDuration is volatile, but we update it without locks
-// or atomics. The code is designed so that _SpinDuration stays within
-// a reasonable range even in the presence of races. The arithmetic
-// operations on _SpinDuration are closed over the domain of legal values,
-// so at worst a race will install and older but still legal value.
-// At the very worst this introduces some apparent non-determinism.
-// We might spin when we shouldn't or vice-versa, but since the spin
-// count are relatively short, even in the worst case, the effect is harmless.
-//
-// Care must be taken that a low "D" value does not become an
-// an absorbing state. Transient spinning failures -- when spinning
-// is overall profitable -- should not cause the system to converge
-// on low "D" values. We want spinning to be stable and predictable
-// and fairly responsive to change and at the same time we don't want
-// it to oscillate, become metastable, be "too" non-deterministic,
-// or converge on or enter undesirable stable absorbing states.
-//
-// We implement a feedback-based control system -- using past behavior
-// to predict future behavior. We face two issues: (a) if the
-// input signal is random then the spin predictor won't provide optimal
-// results, and (b) if the signal frequency is too high then the control
-// system, which has some natural response lag, will "chase" the signal.
-// (b) can arise from multimodal lock hold times. Transient preemption
-// can also result in apparent bimodal lock hold times.
-// Although sub-optimal, neither condition is particularly harmful, as
-// in the worst-case we'll spin when we shouldn't or vice-versa.
-// The maximum spin duration is rather short so the failure modes aren't bad.
-// To be conservative, I've tuned the gain in system to bias toward
-// _not spinning. Relatedly, the system can sometimes enter a mode where it
-// "rings" or oscillates between spinning and not spinning. This happens

-//
-// Spin-then-block strategies ...
-//
-// Thoughts on ways to improve spinning :
-//
-// * Periodically call {psr_}getloadavg() while spinning, and
-// permit unbounded spinning if the load average is <
-// the number of processors. Beware, however, that getloadavg()
-// is exceptionally fast on solaris (about 1/10 the cost of a full
-// spin cycle, but quite expensive on linux. Beware also, that
-// multiple JVMs could "ring" or oscillate in a feedback loop.
-// Sufficient damping would solve that problem.
-//
-// * We currently use spin loops with iteration counters to approximate
-// spinning for some interval. Given the availability of high-precision
-// time sources such as gethrtime(), %TICK, %STICK, RDTSC, etc., we should
-// someday reimplement the spin loops to duration-based instead of iteration-based.
-//
-// * Don't spin if there are more than N = (CPUs/2) threads
-// currently spinning on the monitor (or globally).
-// That is, limit the number of concurrent spinners.
-// We might also limit the # of spinners in the JVM, globally.
-//
-// * If a spinning thread observes _owner change hands it should
-// abort the spin (and park immediately) or at least debit
-// the spin counter by a large "penalty".
-//
-// * Classically, the spin count is either K*(CPUs-1) or is a
-// simple constant that approximates the length of a context switch.
-// We currently use a value -- computed by a special utility -- that
-// approximates round-trip context switch times.
-//
-// * Normally schedctl_start()/_stop() is used to advise the kernel
-// to avoid preempting threads that are running in short, bounded
-// critical sections. We could use the schedctl hooks in an inverted
-// sense -- spinners would set the nopreempt flag, but poll the preempt
-// pending flag. If a spinner observed a pending preemption it'd immediately
-// abort the spin and park. As such, the schedctl service acts as
-// a preemption warning mechanism.
-//
-// * In lieu of spinning, if the system is running below saturation
-// (that is, loadavg() << #cpus), we can instead suppress futile
-// wakeup throttling, or even wake more than one successor at exit-time.
-// The net effect is largely equivalent to spinning. In both cases,
-// contending threads go ONPROC and opportunistically attempt to acquire
-// the lock, decreasing lock handover latency at the expense of wasted
-// cycles and context switching.
-//
-// * We might to spin less after we've parked as the thread will
-// have less $ and TLB affinity with the processor.
-// Likewise, we might spin less if we come ONPROC on a different
-// processor or after a long period (>> rechose_interval).
-//
-// * A table-driven state machine similar to Solaris' dispadmin scheduling
-// tables might be a better design. Instead of encoding information in
-// _SpinDuration, _SpinFreq and _SpinClock we'd just use explicit,
-// discrete states. Success or failure during a spin would drive
-// state transitions, and each state node would contain a spin count.
-//
-// * If the processor is operating in a mode intended to conserve power
-// (such as Intel's SpeedStep) or to reduce thermal output (thermal
-// step-down mode) then the Java synchronization subsystem should
-// forgo spinning.
-//
-// * The minimum spin duration should be approximately the worst-case
-// store propagation latency on the platform. That is, the time
-// it takes a store on CPU A to become visible on CPU B, where A and
-// B are "distant".
-//
-// * We might want to factor a thread's priority in the spin policy.
-// Threads with a higher priority might spin for slightly longer.
-// Similarly, if we use back-off in the TATAS loop, lower priority
-// threads might back-off longer. We don't currently use a
-// thread's priority when placing it on the entry queue. We may
-// want to consider doing so in future releases.
-//
-// * We might transiently drop a thread's scheduling priority while it spins.
-// SCHED_BATCH on linux and FX scheduling class at priority=0 on Solaris
-// would suffice. We could even consider letting the thread spin indefinitely at
-// a depressed or "idle" priority. This brings up fairness issues, however --
-// in a saturated system a thread would with a reduced priority could languish
-// for extended periods on the ready queue.
-//
-// * While spinning try to use the otherwise wasted time to help the VM make
-// progress:
-//
-// -- YieldTo() the owner, if the owner is OFFPROC but ready
-// Done our remaining quantum directly to the ready thread.
-// This helps "push" the lock owner through the critical section.
-// It also tends to improve affinity/locality as the lock
-// "migrates" less frequently between CPUs.
-// -- Walk our own stack in anticipation of blocking. Memoize the roots.
-// -- Perform strand checking for other thread. Unpark potential strandees.
-// -- Help GC: trace or mark -- this would need to be a bounded unit of work.
-// Unfortunately this will pollute our $ and TLBs. Recall that we
-// spin to avoid context switching -- context switching has an
-// immediate cost in latency, a disruptive cost to other strands on a CMT
-// processor, and an amortized cost because of the D$ and TLB cache
-// reload transient when the thread comes back ONPROC and repopulates
-// $s and TLBs.
-// -- call getloadavg() to see if the system is saturated. It'd probably
-// make sense to call getloadavg() half way through the spin.
-// If the system isn't at full capacity the we'd simply reset
-// the spin counter to and extend the spin attempt.
-// -- Doug points out that we should use the same "helping" policy
-// in thread.yield().
-//
-// * Try MONITOR-MWAIT on systems that support those instructions.
-//
-// * The spin statistics that drive spin decisions & frequency are
-// maintained in the objectmonitor structure so if we deflate and reinflate
-// we lose spin state. In practice this is not usually a concern
-// as the default spin state after inflation is aggressive (optimistic)
-// and tends toward spinning. So in the worst case for a lock where
-// spinning is not profitable we may spin unnecessarily for a brief
-// period. But then again, if a lock is contended it'll tend not to deflate
-// in the first place.

-// Theory of operations -- Monitors lists, thread residency, etc:
-//
-// * A thread acquires ownership of a monitor by successfully
-// CAS()ing the _owner field from null to non-null.
-//
-// * Invariant: A thread appears on at most one monitor list --
-// cxq, EntryList or WaitSet -- at any one time.
-//
-// * Contending threads "push" themselves onto the cxq with CAS
-// and then spin/park.
-//
-// * After a contending thread eventually acquires the lock it must
-// dequeue itself from either the EntryList or the cxq.
-//
-// * The exiting thread identifies and unparks an "heir presumptive"
-// tentative successor thread on the EntryList. Critically, the
-// exiting thread doesn't unlink the successor thread from the EntryList.
-// After having been unparked, the wakee will recontend for ownership of
-// the monitor. The successor (wakee) will either acquire the lock or
-// re-park itself.
-//
-// Succession is provided for by a policy of competitive handoff.
-// The exiting thread does _not_ grant or pass ownership to the
-// successor thread. (This is also referred to as "handoff" succession").
-// Instead the exiting thread releases ownership and possibly wakes
-// a successor, so the successor can (re)compete for ownership of the lock.
-// If the EntryList is empty but the cxq is populated the exiting
-// thread will drain the cxq into the EntryList. It does so by
-// by detaching the cxq (installing null with CAS) and folding
-// the threads from the cxq into the EntryList. The EntryList is
-// doubly linked, while the cxq is singly linked because of the
-// CAS-based "push" used to enqueue recently arrived threads (RATs).
-//
-// * Concurrency invariants:
-//
-// -- only the monitor owner may access or mutate the EntryList.
-// The mutex property of the monitor itself protects the EntryList
-// from concurrent interference.
-// -- Only the monitor owner may detach the cxq.
-//
-// * The monitor entry list operations avoid locks, but strictly speaking
-// they're not lock-free. Enter is lock-free, exit is not.
-// See http://j2se.east/~dice/PERSIST/040825-LockFreeQueues.html
-//
-// * The cxq can have multiple concurrent "pushers" but only one concurrent
-// detaching thread. This mechanism is immune from the ABA corruption.
-// More precisely, the CAS-based "push" onto cxq is ABA-oblivious.
-//
-// * Taken together, the cxq and the EntryList constitute or form a
-// single logical queue of threads stalled trying to acquire the lock.
-// We use two distinct lists to improve the odds of a constant-time
-// dequeue operation after acquisition (in the ::enter() epilog) and
-// to reduce heat on the list ends. (c.f. Michael Scott's "2Q" algorithm).
-// A key desideratum is to minimize queue & monitor metadata manipulation
-// that occurs while holding the monitor lock -- that is, we want to
-// minimize monitor lock holds times. Note that even a small amount of
-// fixed spinning will greatly reduce the # of enqueue-dequeue operations
-// on EntryList|cxq. That is, spinning relieves contention on the "inner"
-// locks and monitor metadata.
-//
-// Cxq points to the the set of Recently Arrived Threads attempting entry.
-// Because we push threads onto _cxq with CAS, the RATs must take the form of
-// a singly-linked LIFO. We drain _cxq into EntryList at unlock-time when
-// the unlocking thread notices that EntryList is null but _cxq is != null.
-//
-// The EntryList is ordered by the prevailing queue discipline and
-// can be organized in any convenient fashion, such as a doubly-linked list or
-// a circular doubly-linked list. Critically, we want insert and delete operations
-// to operate in constant-time. If we need a priority queue then something akin
-// to Solaris' sleepq would work nicely. Viz.,
-// http://agg.eng/ws/on10_nightly/source/usr/src/uts/common/os/sleepq.c.
-// Queue discipline is enforced at ::exit() time, when the unlocking thread
-// drains the cxq into the EntryList, and orders or reorders the threads on the
-// EntryList accordingly.
-//
-// Barring "lock barging", this mechanism provides fair cyclic ordering,
-// somewhat similar to an elevator-scan.
-//
-// * The monitor synchronization subsystem avoids the use of native
-// synchronization primitives except for the narrow platform-specific
-// park-unpark abstraction. See the comments in os_solaris.cpp regarding
-// the semantics of park-unpark. Put another way, this monitor implementation
-// depends only on atomic operations and park-unpark. The monitor subsystem
-// manages all RUNNING->BLOCKED and BLOCKED->READY transitions while the
-// underlying OS manages the READY<->RUN transitions.
-//
-// * Waiting threads reside on the WaitSet list -- wait() puts
-// the caller onto the WaitSet.
-//
-// * notify() or notifyAll() simply transfers threads from the WaitSet to
-// either the EntryList or cxq. Subsequent exit() operations will
-// unpark the notifyee. Unparking a notifee in notify() is inefficient -
-// it's likely the notifyee would simply impale itself on the lock held
-// by the notifier.
-//
-// * An interesting alternative is to encode cxq as (List,LockByte) where
-// the LockByte is 0 iff the monitor is owned. _owner is simply an auxiliary
-// variable, like _recursions, in the scheme. The threads or Events that form
-// the list would have to be aligned in 256-byte addresses. A thread would
-// try to acquire the lock or enqueue itself with CAS, but exiting threads
-// could use a 1-0 protocol and simply STB to set the LockByte to 0.
-// Note that is is *not* word-tearing, but it does presume that full-word
-// CAS operations are coherent with intermix with STB operations. That's true
-// on most common processors.

-// ::enter() path, resulting in the entering thread being stranding
-// and a progress-liveness failure. Stranding is extremely rare.
-// We use timers (timed park operations) & periodic polling to detect
-// and recover from stranding. Potentially stranded threads periodically
-// wake up and poll the lock. See the usage of the _Responsible variable.
-//
-// The CAS() in enter provides for safety and exclusion, while the CAS or
-// MEMBAR in exit provides for progress and avoids stranding. 1-0 locking
-// eliminates the CAS/MEMBAR from the exist path, but it admits stranding.
-// We detect and recover from stranding with timers.
+// Release all inflated monitors owned by THREAD. Lightweight monitors are
+// ignored. This is meant to be called during JNI thread detach which assumes
+// all remaining monitors are heavyweight. All exceptions are swallowed.
+// Scanning the extant monitor list can be time consuming.
+// A simple optimization is to add a per-thread flag that indicates a thread
+// called jni_monitorenter() during its lifetime.
//
-// If a thread transiently strands it'll park until (a) another
-// thread acquires the lock and then drops the lock, at which time the
-// exiting thread will notice and unpark the stranded thread, or, (b)
-// the timer expires. If the lock is high traffic then the stranding latency
-// will be low due to (a). If the lock is low traffic then the odds of
-// stranding are lower, although the worst-case stranding latency
-// is longer. Critically, we don't want to put excessive load in the

-// rate (timers created/sec) as well as the number of timers active at
-// any one time. (more precisely, we want to minimize timer-seconds, which is

-// The raw monitor subsystem is entirely distinct from normal
-// java-synchronization or jni-synchronization. raw monitors are not
-// associated with objects. They can be implemented in any manner
-// that makes sense. The original implementors decided to piggy-back
-// the raw-monitor implementation on the existing Java objectMonitor mechanism.
-// This flaw needs to fixed. We should reimplement raw monitors as sui-generis.
-// Specifically, we should not implement raw monitors via java monitors.
-// Time permitting, we should disentangle and deconvolve the two implementations
-// and move the resulting raw monitor implementation over to the JVMTI directories.
-// Ideally, the raw monitor implementation would be built on top of
-// park-unpark and nothing else.
-//
-// raw monitors are used mainly by JVMTI
-// The raw monitor implementation borrows the ObjectMonitor structure,
-// but the operators are degenerate and extremely simple.
-//
-// Mixed use of a single objectMonitor instance -- as both a raw monitor
-// and a normal java monitor -- is not permissible.
-//
-// Note that we use the single RawMonitor_lock to protect queue operations for
-// _all_ raw monitors. This is a scalability impediment, but since raw monitor usage
-// is deprecated and rare, this is not of concern. The RawMonitor_lock can not
-// be held indefinitely. The critical sections must be short and bounded.

+//
+// * The current implementation of muxAcquire-muxRelease uses its own
+// dedicated Thread._MuxEvent instance. If we're interested in
+// minimizing the peak number of extant ParkEvent instances then
+// we could eliminate _MuxEvent and "borrow" _ParkEvent as long
+// as certain invariants were satisfied. Specifically, care would need
+// to be taken with regards to consuming unpark() "permits".
+// A safe rule of thumb is that a thread would never call muxAcquire()
+// if it's enqueued (cxq, EntryList, WaitList, etc) and will subsequently
+// park(). Otherwise the _ParkEvent park() operation in muxAcquire() could
+// consume an unpark() permit intended for monitorenter, for instance.
+// One way around this would be to widen the restricted-range semaphore
+// implemented in park(). Another alternative would be to provide
+// multiple instances of the PlatformEvent() for each thread. One
+// instance would be dedicated to muxAcquire-muxRelease, for instance.
+//
+// * Usage:
+// -- Only as leaf locks
+// -- for short-term locking only as muxAcquire does not perform
+// thread state transitions.
+//
+// Alternatives:
+// * We could implement muxAcquire and muxRelease with MCS or CLH locks
+// but with parking or spin-then-park instead of pure spinning.
+// * Use Taura-Oyama-Yonenzawa locks.
+// * It's possible to construct a 1-0 lock if we encode the lockword as
+// (List,LockByte). Acquire will CAS the full lockword while Release
+// will STB 0 into the LockByte. The 1-0 scheme admits stranding, so
+// acquiring threads use timers (ParkTimed) to detect and recover from
+// the stranding window. Thread/Node structures must be aligned on 256-byte
+// boundaries by using placement-new.
+// * Augment MCS with advisory back-link fields maintained with CAS().
+// Pictorially: LockWord -> T1 <-> T2 <-> T3 <-> ... <-> Tn <-> Owner.
+// The validity of the backlinks must be ratified before we trust the value.
+// If the backlinks are invalid the exiting thread must back-track through the
+// the forward links, which are always trustworthy.
+// * Add a successor indication. The LockWord is currently encoded as
+// (List, LOCKBIT:1). We could also add a SUCCBIT or an explicit _succ variable
+// to provide the usual futile-wakeup optimization.
+// See RTStt for details.

-// ParkEvents are type-stable and immortal.
-//
-// Lifecycle: Once a ParkEvent is associated with a thread that ParkEvent remains
-// associated with the thread for the thread's entire lifetime - the relationship is
-// stable. A thread will be associated at most one ParkEvent. When the thread
-// expires, the ParkEvent moves to the EventFreeList. New threads attempt to allocate from
-// the EventFreeList before creating a new Event. Type-stability frees us from
-// worrying about stale Event or Thread references in the objectMonitor subsystem.
-// (A reference to ParkEvent is always valid, even though the event may no longer be associated
-// with the desired or expected thread. A key aspect of this design is that the callers of
-// park, unpark, etc must tolerate stale references and spurious wakeups).
-//
-// Only the "associated" thread can block (park) on the ParkEvent, although
-// any other thread can unpark a reachable parkevent. Park() is allowed to
-// return spuriously. In fact park-unpark a really just an optimization to
-// avoid unbounded spinning and surrender the CPU to be a polite system citizen.
-// A degenerate albeit "impolite" park-unpark implementation could simply return.
-// See http://blogs.sun.com/dave for more details.
-//
-// Eventually I'd like to eliminate Events and ObjectWaiters, both of which serve as
-// thread proxies, and simply make the THREAD structure type-stable and persistent.
-// Currently, we unpark events associated with threads, but ideally we'd just
-// unpark threads.
-//
-// The base-class, PlatformEvent, is platform-specific while the ParkEvent is
-// platform-independent. PlatformEvent provides park(), unpark(), etc., and
-// is abstract -- that is, a PlatformEvent should never be instantiated except
-// as part of a ParkEvent.
-// Equivalently we could have defined a platform-independent base-class that
-// exported Allocate(), Release(), etc. The platform-specific class would extend
-// that base-class, adding park(), unpark(), etc.
-//
-// A word of caution: The JVM uses 2 very similar constructs:
-// 1. ParkEvent are used for Java-level "monitor" synchronization.
-// 2. Parkers are used by JSR166-JUC park-unpark.

- * Every linked {@code CallSite} object corresponds to a distinct instance
- * of the {@code invokedynamic} instruction, and vice versa.
- * <p>
- * Every linked {@code CallSite} object has one state variable,
- * a {@link MethodHandle} reference called the {@code target}.
- * This reference is never null. Though it can change its value
- * successive values must always have exactly the {@link MethodType method type}
- * called for by the bytecodes of the associated {@code invokedynamic} instruction
- * <p>
- * It is the responsibility of each class's
- * {@link Linkage#registerBootstrapMethod(Class, MethodHandle) bootstrap method}
- * to produce call sites which have been pre-linked to an initial target method.
- * The required {@link MethodType type} for the target method is a parameter
- * to each bootstrap method call.
- * <p>
- * The bootstrap method may elect to produce call sites of a
- * language-specific subclass of {@code CallSite}. In such a case,
- * the subclass may claim responsibility for initializing its target to
- * a non-null value, by overriding {@link #initialTarget}.
+ * A {@code CallSite} is a holder for a variable {@link MethodHandle},
+ * which is called its {@code target}.
+ * Every call to a {@code CallSite} is delegated to the site's current target.
* <p>
- * An {@code invokedynamic} instruction which has not yet been executed
- * is said to be <em>unlinked</em>. When an unlinked call site is executed,
- * the containing class's bootstrap method is called to manufacture a call site,
- * for the instruction. If the bootstrap method does not assign a non-null
- * value to the new call site's target variable, the method {@link #initialTarget}
- * is called to produce the new call site's first target method.
+ * A call site is initially created in an <em>unlinked</em> state,
+ * which is distinguished by a null target variable.
+ * Before the call site may be invoked (and before certain other
+ * operations are attempted), the call site must be linked to
+ * a non-null target.
* <p>
- * A freshly-created {@code CallSite} object is not yet in a linked state.
- * An unlinked {@code CallSite} object reports null for its {@code callerClass}.
- * When the JVM receives a {@code CallSite} object from a bootstrap method,
- * it first ensures that its target is non-null and of the correct type.
- * The JVM then links the {@code CallSite} object to the call site instruction,
- * enabling the {@code callerClass} to return the class in which the instruction occurs.
- * <p>
- * Next, the JVM links the instruction to the {@code CallSite}, at which point
- * any further execution of the {@code invokedynamic} instruction implicitly
- * invokes the current target of the {@code CallSite} object.
- * After this two-way linkage, both the instruction and the {@code CallSite}
- * object are said to be linked.
- * <p>
- * This state of linkage continues until the method containing the
- * dynamic call site is garbage collected, or the dynamic call site
- * is invalidated by an explicit request.
+ * A call site may be <em>relinked</em> by changing its target.
+ * The new target must be non-null and must have the same
+ * {@linkplain MethodHandle#type() type}
+ * as the previous target.
+ * Thus, though a call site can be relinked to a series of

-/**
- * A Java method handle is a deprecated proposal for extending
- * the basic method handle type with additional
- * programmer defined methods and fields.
- * Its behavior as a method handle is determined at instance creation time,
- * by providing the new instance with an "entry point" method handle
- * to handle calls. This entry point must accept a leading argument
- * whose type is the Java method handle itself or a supertype, and the
- * entry point is always called with the Java method handle itself as
- * the first argument. This is similar to ordinary virtual methods, which also
- * accept the receiver object {@code this} as an implicit leading argument.
- * The {@code MethodType} of the Java method handle is the same as that
- * of the entry point method handle, with the leading parameter type
- * omitted.
- * <p>
- * Here is an example of usage, creating a hybrid object/functional datum:
- * <p><blockquote><pre>
- * class Greeter extends JavaMethodHandle {
- * private String greeting = "hello";
- * public void setGreeting(String s) { greeting = s; }
- * public void run() { System.out.println(greeting+", "+greetee); }
- * private final String greetee;
- * Greeter(String greetee) {
- * super(RUN); // alternatively, super("run")
- * this.greetee = greetee;
- * }
- * // the entry point function is computed once:
- * private static final MethodHandle RUN
- * = MethodHandles.lookup().findVirtual(Greeter.class, "run",
- * MethodType.make(void.class));
- * }
- * // class Main { public static void main(String... av) { ...
- * Greeter greeter = new Greeter("world");
- * greeter.run(); // prints "hello, world"
- * // Statically typed method handle invocation (most direct):
- * MethodHandle mh = greeter;
- * mh.<void>invokeExact(); // also prints "hello, world"
- * // Dynamically typed method handle invocation:
- * MethodHandles.invokeExact(greeter); // also prints "hello, world"
- * greeter.setGreeting("howdy");
- * mh.invokeExact(); // prints "howdy, world" (object-like mutable behavior)
- * </pre></blockquote>
- * <p>
- * In the example of {@code Greeter}, the method {@code run} provides the entry point.
- * The entry point need not be a constant value; it may be independently
- * computed in each call to the constructor. The entry point does not
- * even need to be a method on the {@code Greeter} class, though
- * that is the typical case.
- * <p>
- * The entry point may also be provided symbolically, in which case the the
- * {@code JavaMethodHandle} constructor performs the lookup of the entry point.
- * This makes it possible to use {@code JavaMethodHandle} to create an anonymous
- * inner class:
- * <p><blockquote><pre>
- * // We can also do this with symbolic names and/or inner classes:
- * MethodHandles.invokeExact(new JavaMethodHandle("yow") {
- * void yow() { System.out.println("yow, world"); }
- * });
- * </pre></blockquote>
- * <p>
- * Here is similar lower-level code which works in terms of a bound method handle.
- * <p><blockquote><pre>
- * class Greeter {
- * public void run() { System.out.println("hello, "+greetee); }
- * private final String greetee;
- * Greeter(String greetee) { this.greetee = greetee; }
- * // the entry point function is computed once:
- * private static final MethodHandle RUN
- * = MethodHandles.findVirtual(Greeter.class, "run",
- * MethodType.make(void.class));
- * }
- * // class Main { public static void main(String... av) { ...
- * Greeter greeter = new Greeter("world");
- * greeter.run(); // prints "hello, world"
- * MethodHandle mh = MethodHanndles.insertArgument(Greeter.RUN, 0, greeter);
- * mh.invokeExact(); // also prints "hello, world"
- * </pre></blockquote>
- * Note that the method handle must be separately created as a view on the base object.
- * This increases footprint, complexity, and dynamic indirections.
- * <p>
- * Here is a pure functional value expressed most concisely as an anonymous inner class:
- * <p><blockquote><pre>
- * // class Main { public static void main(String... av) { ...
- * final String greetee = "world";
- * MethodHandle greeter = new JavaMethodHandle("run") {
- * private void run() { System.out.println("hello, "+greetee); }
- * }
- * greeter.invokeExact(); // prints "hello, world"
- * </pre></blockquote>
- * <p>
- * Here is an abstract parameterized lvalue, efficiently expressed as a subtype of MethodHandle,
- * and instantiated as an anonymous class. The data structure is a handle to 1-D array,
- * with a specialized index type (long). It is created by inner class, and uses
- * signature-polymorphic APIs throughout.
- * <p><blockquote><pre>
- * abstract class AssignableMethodHandle extends JavaMethodHandle {
- * private final MethodHandle setter;
- * public MethodHandle setter() { return setter; }
- * public AssignableMethodHandle(String get, String set) {
- * super(get);
- * MethodType getType = this.type();
- * MethodType setType = getType.insertParameterType(getType.parameterCount(), getType.returnType()).changeReturnType(void.class);
- * this.setter = MethodHandles.publicLookup().bind(this, set, setType);
- * }
- * }
- * // class Main { public static void main(String... av) { ...
- * final Number[] stuff = { 123, 456 };
- * AssignableMethodHandle stuffPtr = new AssignableMethodHandle("get", "set") {
- * public Number get(long i) { return stuff[(int)i]; }
- * public void set(long i, Object x) { stuff[(int)i] = x; }
- * }
- * int x = (Integer) stuffPtr.<Number>invokeExact(1L); // 456
- * stuffPtr.setter().<void>invokeExact(0L, (Number) 789); // replaces 123 with 789
- * </pre></blockquote>

*
+ * <h2><a name="bsm"></a>Bootstrap Methods</h2>
+ * Before the JVM can execute a dynamic call site (an {@code invokedynamic} instruction),
+ * the call site must first be <em>linked</em>.
+ * Linking is accomplished by calling a <em>bootstrap method</em>
+ * which is given the static information content of the call site,
+ * and which must produce a {@link java.dyn.MethodHandle method handle}
+ * that gives the behavior of the call site.
+ * <p>
+ * Each {@code invokedynamic} instruction statically specifies its own
+ * bootstrap method as a constant pool reference.
+ * The constant pool reference also specifies the call site's name and type signature,
+ * just like {@code invokevirtual} and the other invoke instructions.
+ * <p>
+ * Linking starts with resolving the constant pool entry for the
+ * bootstrap method, and resolving a {@link java.dyn.MethodType MethodType} object for
+ * the type signature of the dynamic call site.
+ * This resolution process may trigger class loading.
+ * It may therefore throw an error if a class fails to load.
+ * This error becomes the abnormal termination of the dynamic
+ * call site execution.
+ * Linkage does not trigger class initialization.
+ * <p>
+ * Next, the bootstrap method call is started, with four values being stacked:
+ * <ul>
+ * <li>a {@code MethodHandle}, the resolved bootstrap method itself </li>
+ * <li>a {@code Class}, the <em>caller class</em> in which dynamic call site occurs </li>
+ * <li>a {@code String}, the method name mentioned in the call site </li>
+ * <li>a {@code MethodType}, the resolved type signature of the call </li>
+ * </ul>
+ * The method handle is then applied to the other values as if by
+ * {@linkplain java.dyn.MethodHandle#invokeGeneric the <code>invokeGeneric</code> method}.
+ * The returned result must be a {@link java.dyn.CallSite CallSite}, a {@link java.dyn.MethodHandle MethodHandle},
+ * or another {@link java.dyn.MethodHandleProvider MethodHandleProvider} value.
+ * The method {@linkplain java.dyn.MethodHandleProvider#asMethodHandle asMethodHandle}
+ * is then called on the returned value. The result of that second
+ * call is the {@code MethodHandle} which becomes the
+ * permanent binding for the dynamic call site.
+ * That method handle's type must be exactly equal to the type
+ * derived from the dynamic call site signature and passed to
+ * the bootstrap method.
+ * <p>
+ * After resolution, the linkage process may fail in a variety of ways.
+ * All failures are reported by an {@link java.dyn.InvokeDynamicBootstrapError InvokeDynamicBootstrapError},
+ * which is thrown as the abnormal termination of the dynamic call
+ * site execution.
+ * The following circumstances will cause this:
+ * <ul>
+ * <li>the bootstrap method invocation completes abnormally </li>
+ * <li>the result from the bootstrap invocation is not a reference to
+ * an object of type {@link java.dyn.MethodHandleProvider MethodHandleProvider} </li>
+ * <li>the call to {@code asMethodHandle} completes abnormally </li>
+ * <li>the call to {@code asMethodHandle} fails to return a reference to
+ * an object of type {@link java.dyn.MethodHandle MethodHandle} </li>
+ * <li>the method handle produced by {@code asMethodHandle} does not have
+ * the expected {@code MethodType} </li>
+ * </ul>
+ * <h3>timing of linkage</h3>
+ * A dynamic call site is linked just before its first execution.
+ * The bootstrap method call implementing the linkage occurs within
+ * a thread that is attempting a first execution.
+ * <p>
+ * If there are several such threads, the JVM picks one thread
+ * and runs the bootstrap method while the others wait for the
+ * invocation to terminate normally or abnormally.
+ * <p>
+ * After a bootstrap method is called and a method handle target
+ * successfully extracted, the JVM attempts to link the instruction
+ * being executed to the target method handle.
+ * This may fail if there has been intervening linkage
+ * or invalidation event for the same instruction.
+ * If such a failure occurs, the dynamic call site must be
+ * re-executed from the beginning, either re-linking it
+ * (if it has been invalidated) or invoking the target
+ * (if it the instruction has been linked by some other means).
+ * <p>
+ * If the instruction is linked successfully, the target method
+ * handle is invoked to complete the instruction execution.
+ * The state of linkage continues until the method containing the
+ * dynamic call site is garbage collected, or the dynamic call site
+ * is invalidated by an explicit request,
+ * such as {@link java.dyn.Linkage#invalidateCallerClass Linkage.invalidateCallerClass}.
+ * <p>
+ * In an application which requires dynamic call sites with individually
+ * mutable behaviors, their bootstrap methods should produce distinct
+ * {@link java.dyn.CallSite CallSite} objects, one for each linkage request.
+ * <p>
+ * If a class containing {@code invokedynamic} instructions
+ * is {@linkplain java.dyn.Linkage#invalidateCallerClass(Class) invalidated},
+ * subsequent execution of those {@code invokedynamic} instructions
+ * will require linking.
+ * It is as if they had never been executed in the first place.
+ * (However, invalidation does not cause constant pool entries to be
+ * resolved a second time.)
+ * <p>
+ * Invalidation events and bootstrap method calls for a particular
+ * dynamic call site are globally ordered relative to each other.
+ * When an invokedynamic instruction is invalidated, if there is
+ * simultaneously a bootstrap method invocation in process
+ * (in the same thread or a different thread), the result
+ * eventually returned must not be used to link the call site.
+ * Put another way, when a call site is invalidated, its
+ * subsequent linkage (if any) must be performed by a bootstrap method
+ * call initiated after the invalidation occurred.
+ * <p>
+ * If several threads simultaneously execute a bootstrap method for a single dynamic
+ * call site, the JVM must choose one target object and installs it visibly to
+ * all threads. Any other bootstrap method calls are allowed to complete, but their
+ * results are ignored, and their dynamic call site invocations proceed with the originally
+ * chosen target object.
+ * <p>
+ * The JVM is free to duplicate dynamic call sites.
+ * This means that, even if a class contains just one {@code invokedynamic}
+ * instruction, its bootstrap method may be executed several times,
+ * once for each duplicate. Thus, bootstrap method code should not
+ * assume an exclusive one-to-one correspondence between particular occurrences
+ * of {@code invokedynamic} bytecodes in class files and linkage events.
+ * <p>
+ * In principle, each individual execution of an {@code invokedynamic}
+ * instruction could be deemed (by a conforming implementation) to be a separate
+ * duplicate, requiring its own execution of the bootstrap method.
+ * However, implementations are expected to perform code duplication
+ * (if at all) in order to improve performance, not make it worse.
+ *

-/**
- * An asynchronous channel for datagram-oriented sockets.
- *
- * <p> An asynchronous datagram channel is created by invoking one of the {@link
- * #open open} methods defined by this class. It is not possible to create a channel
- * for an arbitrary, pre-existing datagram socket. A newly-created asynchronous
- * datagram channel is open but not connected. It need not be connected in order
- * for the {@link #send send} and {@link #receive receive} methods to be used.
- * A datagram channel may be connected, by invoking its {@link #connect connect}
- * method, in order to avoid the overhead of the security checks that are otherwise
- * performed as part of every send and receive operation when a security manager
- * is set. The channel must be connected in order to use the {@link #read read}
- * and {@link #write write} methods, since those methods do not accept or return
- * socket addresses. Once connected, an asynchronous datagram channel remains
- * connected until it is disconnected or closed.
- *
- * <p> Socket options are configured using the {@link #setOption(SocketOption,Object)
- * setOption} method. An asynchronous datagram channel to an Internet Protocol
- * (IP) socket supports the following options:
- * <blockquote>
- * <table border>
- * <tr>
- * <th>Option Name</th>
- * <th>Description</th>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#SO_SNDBUF SO_SNDBUF} </td>
- * <td> The size of the socket send buffer </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#SO_RCVBUF SO_RCVBUF} </td>
- * <td> The size of the socket receive buffer </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#SO_REUSEADDR SO_REUSEADDR} </td>
- * <td> Re-use address </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#SO_BROADCAST SO_BROADCAST} </td>
- * <td> Allow transmission of broadcast datagrams </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#IP_TOS IP_TOS} </td>
- * <td> The Type of Service (ToS) octet in the Internet Protocol (IP) header </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#IP_MULTICAST_IF IP_MULTICAST_IF} </td>
- * <td> The network interface for Internet Protocol (IP) multicast datagrams </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#IP_MULTICAST_TTL
- * IP_MULTICAST_TTL} </td>
- * <td> The <em>time-to-live</em> for Internet Protocol (IP) multicast
- * datagrams </td>
- * </tr>
- * <tr>
- * <td> {@link java.net.StandardSocketOption#IP_MULTICAST_LOOP
- * IP_MULTICAST_LOOP} </td>
- * <td> Loopback for Internet Protocol (IP) multicast datagrams </td>
- * </tr>
- * </table>
- * </blockquote>
- * Additional (implementation specific) options may also be supported.
- *
- * <p> Asynchronous datagram channels allow more than one read/receive and
- * write/send to be oustanding at any given time.
- *
- * <p> <b>Usage Example:</b>
- * <pre>
- * final AsynchronousDatagramChannel dc = AsynchronousDatagramChannel.open()
- * .bind(new InetSocketAddress(4000));
- *
- * // print the source address of all packets that we receive
- * dc.receive(buffer, buffer, new CompletionHandler<SocketAddress,ByteBuffer>() {
- * public void completed(SocketAddress sa, ByteBuffer buffer) {
- * System.out.println(sa);
- * buffer.clear();
- * dc.receive(buffer, buffer, this);
- * }
- * public void failed(Throwable exc, ByteBuffer buffer) {
- * ...
- * }
- * });

+/**
+ * A Java method handle is a deprecated proposal for extending
+ * the basic method handle type with additional
+ * programmer defined methods and fields.
+ * Its behavior as a method handle is determined at instance creation time,
+ * by providing the new instance with an "entry point" method handle
+ * to handle calls. This entry point must accept a leading argument
+ * whose type is the Java method handle itself or a supertype, and the
+ * entry point is always called with the Java method handle itself as
+ * the first argument. This is similar to ordinary virtual methods, which also
+ * accept the receiver object {@code this} as an implicit leading argument.
+ * The {@code MethodType} of the Java method handle is the same as that
+ * of the entry point method handle, with the leading parameter type
+ * omitted.
+ * <p>
+ * Here is an example of usage, creating a hybrid object/functional datum:
+ * <p><blockquote><pre>
+ * class Greeter extends JavaMethodHandle {
+ * private String greeting = "hello";
+ * public void setGreeting(String s) { greeting = s; }
+ * public void run() { System.out.println(greeting+", "+greetee); }
+ * private final String greetee;
+ * Greeter(String greetee) {
+ * super(RUN); // alternatively, super("run")
+ * this.greetee = greetee;
+ * }
+ * // the entry point function is computed once:
+ * private static final MethodHandle RUN
+ * = MethodHandles.lookup().findVirtual(Greeter.class, "run",
+ * MethodType.make(void.class));
+ * }
+ * // class Main { public static void main(String... av) { ...
+ * Greeter greeter = new Greeter("world");
+ * greeter.run(); // prints "hello, world"
+ * // Statically typed method handle invocation (most direct):
+ * MethodHandle mh = greeter;
+ * mh.<void>invokeExact(); // also prints "hello, world"
+ * // Dynamically typed method handle invocation:
+ * MethodHandles.invokeExact(greeter); // also prints "hello, world"
+ * greeter.setGreeting("howdy");
+ * mh.invokeExact(); // prints "howdy, world" (object-like mutable behavior)
+ * </pre></blockquote>
+ * <p>
+ * In the example of {@code Greeter}, the method {@code run} provides the entry point.
+ * The entry point need not be a constant value; it may be independently
+ * computed in each call to the constructor. The entry point does not
+ * even need to be a method on the {@code Greeter} class, though
+ * that is the typical case.
+ * <p>
+ * The entry point may also be provided symbolically, in which case the the
+ * {@code JavaMethodHandle} constructor performs the lookup of the entry point.
+ * This makes it possible to use {@code JavaMethodHandle} to create an anonymous
+ * inner class:
+ * <p><blockquote><pre>
+ * // We can also do this with symbolic names and/or inner classes:
+ * MethodHandles.invokeExact(new JavaMethodHandle("yow") {
+ * void yow() { System.out.println("yow, world"); }
+ * });
+ * </pre></blockquote>
+ * <p>
+ * Here is similar lower-level code which works in terms of a bound method handle.
+ * <p><blockquote><pre>
+ * class Greeter {
+ * public void run() { System.out.println("hello, "+greetee); }
+ * private final String greetee;
+ * Greeter(String greetee) { this.greetee = greetee; }
+ * // the entry point function is computed once:
+ * private static final MethodHandle RUN
+ * = MethodHandles.findVirtual(Greeter.class, "run",
+ * MethodType.make(void.class));
+ * }
+ * // class Main { public static void main(String... av) { ...
+ * Greeter greeter = new Greeter("world");
+ * greeter.run(); // prints "hello, world"
+ * MethodHandle mh = MethodHanndles.insertArgument(Greeter.RUN, 0, greeter);
+ * mh.invokeExact(); // also prints "hello, world"
+ * </pre></blockquote>
+ * Note that the method handle must be separately created as a view on the base object.
+ * This increases footprint, complexity, and dynamic indirections.
+ * <p>
+ * Here is a pure functional value expressed most concisely as an anonymous inner class:
+ * <p><blockquote><pre>
+ * // class Main { public static void main(String... av) { ...
+ * final String greetee = "world";
+ * MethodHandle greeter = new JavaMethodHandle("run") {
+ * private void run() { System.out.println("hello, "+greetee); }
+ * }
+ * greeter.invokeExact(); // prints "hello, world"
+ * </pre></blockquote>
+ * <p>
+ * Here is an abstract parameterized lvalue, efficiently expressed as a subtype of MethodHandle,
+ * and instantiated as an anonymous class. The data structure is a handle to 1-D array,
+ * with a specialized index type (long). It is created by inner class, and uses
+ * signature-polymorphic APIs throughout.
+ * <p><blockquote><pre>
+ * abstract class AssignableMethodHandle extends JavaMethodHandle {
+ * private final MethodHandle setter;
+ * public MethodHandle setter() { return setter; }
+ * public AssignableMethodHandle(String get, String set) {
+ * super(get);
+ * MethodType getType = this.type();
+ * MethodType setType = getType.insertParameterType(getType.parameterCount(), getType.returnType()).changeReturnType(void.class);
+ * this.setter = MethodHandles.publicLookup().bind(this, set, setType);
+ * }
+ * }
+ * // class Main { public static void main(String... av) { ...
+ * final Number[] stuff = { 123, 456 };
+ * AssignableMethodHandle stuffPtr = new AssignableMethodHandle("get", "set") {
+ * public Number get(long i) { return stuff[(int)i]; }
+ * public void set(long i, Object x) { stuff[(int)i] = x; }
+ * }
+ * int x = (Integer) stuffPtr.<Number>invokeExact(1L); // 456
+ * stuffPtr.setter().<void>invokeExact(0L, (Number) 789); // replaces 123 with 789
+ * </pre></blockquote>
+ * @see MethodHandle
+ * @deprecated The JSR 292 EG intends to replace {@code JavaMethodHandle} with
+ * an interface-based API for mixing method handle behavior with other classes.
+ * @author John Rose, JSR 292 EG

+// 4 variables: the x and y components of p2p and p3p (i.e. x2p, y2p, x3p, y3p).
+//
+// 2. Bp should have slope equal in absolute value to I at the endpoints. So,
+// (by the way, the operator || in the comments below means "aligned with".
+// It is defined on vectors, so when we say I'(0) || Bp'(0) we mean that
+// vectors I'(0) and Bp'(0) are aligned, which is the same as saying
+// that the tangent lines of I and Bp at 0 are parallel. Mathematically
+// this means (I'(t) || Bp'(t)) <==> (I'(t) = c * Bp'(t)) where c is some
+// nonzero constant.)
+// I'(0) || Bp'(0) and I'(1) || Bp'(1). Obviously, I'(0) || B'(0) and
+// I'(1) || B'(1); therefore, Bp'(0) || B'(0) and Bp'(1) || B'(1).
+// We know that Bp'(0) || (p2p-p1p) and Bp'(1) || (p4p-p3p) and the same
+// is true for any bezier curve; therefore, we get the equations
+// (1) p2p = c1 * (p2-p1) + p1p
+// (2) p3p = c2 * (p4-p3) + p4p
+// We know p1p, p4p, p2, p1, p3, and p4; therefore, this reduces the number
+// of unknowns from 4 to 2 (i.e. just c1 and c2).
+// To eliminate these 2 unknowns we use the following constraint:
+//
+// 3. Bp(0.5) == I(0.5). Bp(0.5)=(x,y) and I(0.5)=(xi,yi), and I should note
+// that I(0.5) is *the only* reason for computing dxm,dym. This gives us
+// (3) Bp(0.5) = (p1p + 3 * (p2p + p3p) + p4p)/8, which is equivalent to
+// (4) p2p + p3p = (Bp(0.5)*8 - p1p - p4p) / 3
+// We can substitute (1) and (2) from above into (4) and we get:
+// (5) c1*(p2-p1) + c2*(p4-p3) = (Bp(0.5)*8 - p1p - p4p)/3 - p1p - p4p

@@ -36,51 +42,161 @@
*
* This class transparently deals with cloneable and non-cloneable digests.
*
+ * This class now supports TLS 1.2 also. The key difference for TLS 1.2
+ * is that you cannot determine the hash algorithms for CertificateVerify
+ * at a early stage. On the other hand, it's simpler than TLS 1.1 (and earlier)
+ * that there is no messy MD5+SHA1 digests.
+ *
+ * You need to obey these conventions when using this class:
+ *
+ * 1. protocolDetermined(boolean isTLS12) should be called when the negotiated
+ * protocol version is determined.
+ *
+ * 2. Before protocolDetermined() is called, only update(), reset(),
+ * restrictCertificateVerifyAlgs(), setFinishedAlg(), and
+ * setCertificateVerifyAlg() can be called.
+ *
+ * 3. After protocolDetermined(*) is called. reset() cannot be called.
+ *
+ * 4. After protocolDetermined(false) is called, getFinishedHash() and
+ * getCertificateVerifyHash() cannot be called. After protocolDetermined(true)
+ * is called, getMD5Clone() and getSHAClone() cannot be called.
+ *
+ * 5. getMD5Clone() and getSHAClone() can only be called after
+ * protocolDetermined(false) is called.
+ *
+ * 6. getFinishedHash() and getCertificateVerifyHash() can only be called after
+ * all protocolDetermined(true), setCertificateVerifyAlg() and setFinishedAlg()
+ * have been called. If a CertificateVerify message is to be used, call
+ * setCertificateVerifyAlg() with the hash algorithm as the argument.
+ * Otherwise, you still must call setCertificateVerifyAlg(null) before
+ * calculating any hash value.
+ *
+ * Suggestions: Call protocolDetermined(), restrictCertificateVerifyAlgs(),
+ * setFinishedAlg(), and setCertificateVerifyAlg() as early as possible.
+ *
+ * Example:
+ * <pre>
+ * HandshakeHash hh = new HandshakeHash(...)
+ * hh.update(clientHelloBytes);
+ * hh.setFinishedAlg("SHA-256");
+ * hh.update(serverHelloBytes);
+ * ...
+ * hh.setCertificateVerifyAlg("SHA-384");
+ * hh.update(CertificateVerifyBytes);
+ * byte[] cvDigest = hh.getCertificateVerifyHash();
+ * ...
+ * hh.update(finished1);
+ * byte[] finDigest1 = hh.getFinishedHash();
+ * hh.update(finished2);
+ * byte[] finDigest2 = hh.getFinishedHash();
+ * </pre>
+ * If no CertificateVerify message is to be used, call
+ * <pre>
+ * hh.setCertificateVerifyAlg(null);
+ * </pre>
+ * This call can be made once you are certain that this message
+ * will never be used.

+
+# Algorithm restrictions for Secure Socket Layer/Transport Layer Security
+# (SSL/TLS) processing
+#
+# In some environments, certain algorithms or key lengths may be undesirable
+# when using SSL/TLS. This section describes the mechanism for disabling
+# algorithms during SSL/TLS security parameters negotiation, including cipher
+# suites selection, peer authentication and key exchange mechanisms.
+#
+# For PKI-based peer authentication and key exchange mechanisms, this list
+# of disabled algorithms will also be checked during certification path
+# building and validation, including algorithms used in certificates, as
+# well as revocation information such as CRLs and signed OCSP Responses.
+# This is in addition to the jdk.certpath.disabledAlgorithms property above.
+#
+# See the specification of "jdk.certpath.disabledAlgorithms" for the
+# syntax of the disabled algorithm string.
+#
+# Note: This property is currently used by Oracle's JSSE implementation.
+# It is not guaranteed to be examined and used by other implementations.
+#
+# Example:
+# jdk.tls.disabledAlgorithms=MD5, SHA1, DSA, RSA keySize < 2048

-/**
- * This class is an abstract annotation processor designed to be a
- * convenient superclass for concrete "type processors", processors that
- * require the type information in the processed source.
- *
- * <p>Type processing occurs in one round after the tool (e.g. java compiler)
- * analyzes the source (all sources taken as input to the tool and sources
- * generated by other annotation processors).
- *
- * <p>The tool infrastructure will interact with classes extending this abstract
- * class as follows:
- *
- * <ol>
- * [1-3: Identical to {@link Processor} life cycle]
- *
- * <li>If an existing {@code Processor} object is not being used, to
- * create an instance of a processor the tool calls the no-arg
- * constructor of the processor class.
- *
- * <li>Next, the tool calls the {@link #init init} method with
- * an appropriate {@code ProcessingEnvironment}.
- *
- * <li>Afterwards, the tool calls {@link #getSupportedAnnotationTypes
- * getSupportedAnnotationTypes}, {@link #getSupportedOptions
- * getSupportedOptions}, and {@link #getSupportedSourceVersion
- * getSupportedSourceVersion}. These methods are only called once per
- * run, not on each round.
- *
- * [4-5Unique to {@code AbstractTypeProcessor} subclasses]
- *
- * <li>For each class containing a supported annotation, the tool calls
- * {@link #typeProcess(TypeElement, TreePath) typeProcess} method on the
- * {@code Processor}. The class is guaranteed to be type-checked Java code
- * and all the tree type and symbol information is resolved.
- *
- * <li>Finally, the tools calls the
- * {@link #typeProcessingOver() typeProcessingOver} method
- * on the {@code Processor}.
- *
- * </ol>
- *
- * <p>The tool is permitted to ask type processors to process a class once
- * it is analyzed before the rest of classes are analyzed. The tool is also
- * permitted to stop type processing immediately if any errors are raised,
- * without invoking {@code typeProcessingOver}
- *
- * <p>A subclass may override any of the methods in this class, as long as the
- * general {@link javax.annotation.processing.Processor Processor}
- * contract is obeyed, with one notable exception.
- * {@link #process(Set, RoundEnvironment)} may not be overridden, as it
- * is called during the regular annotation phase before classes are analyzed.
