+// There are three command line options related to the young gen size:

+// basically only limit the range within which G1 can pick a young gen
+// size. Also, these are general options taking byte sizes. G1 will
+// internally work with a number of regions instead. So, some rounding
+// will occur.
+//
+// If nothing related to the the young gen size is set on the command
+// line we should allow the young gen to be between G1NewSizePercent
+// and G1MaxNewSizePercent of the heap size. This means that every time
+// the heap size changes, the limits for the young gen size will be
+// recalculated.

+// If only -XX:NewSize is set we should use the specified value as the

+ // Spin to avoid context switching.
+ // There's a tension between allowing the mutators to run (and rendezvous)
+ // vs spinning. As the VM thread spins, wasting cycles, it consumes CPU that
+ // a mutator might otherwise use profitably to reach a safepoint. Excessive
+ // spinning by the VM thread on a saturated system can increase rendezvous latency.
+ // Blocking or yielding incur their own penalties in the form of context switching
+ // and the resultant loss of $ residency.
+ //
+ // Further complicating matters is that yield() does not work as naively expected
+ // on many platforms -- yield() does not guarantee that any other ready threads
+ // will run. As such we revert to naked_short_sleep() after some number of iterations.
+ // nakes_short_sleep() is implemented as a short unconditional sleep.
+ // Typical operating systems round a "short" sleep period up to 10 msecs, so sleeping
+ // can actually increase the time it takes the VM thread to detect that a system-wide
+ // stop-the-world safepoint has been reached. In a pathological scenario such as that
+ // described in CR6415670 the VMthread may sleep just before the mutator(s) become safe.
+ // In that case the mutators will be stalled waiting for the safepoint to complete and the
+ // the VMthread will be sleeping, waiting for the mutators to rendezvous. The VMthread
+ // will eventually wake up and detect that all mutators are safe, at which point
+ // we'll again make progress.
+ //
+ // Beware too that that the VMThread typically runs at elevated priority.
+ // Its default priority is higher than the default mutator priority.
+ // Obviously, this complicates spinning.
+ //
+ // Note too that on Windows XP SwitchThreadTo() has quite different behavior than Sleep(0).
+ // Sleep(0) will _not yield to lower priority threads, while SwitchThreadTo() will.
+ //
+ // See the comments in synchronizer.cpp for additional remarks on spinning.
+ //
+ // In the future we might:
+ // 1. Modify the safepoint scheme to avoid potentially unbounded spinning.
+ // This is tricky as the path used by a thread exiting the JVM (say on
+ // on JNI call-out) simply stores into its state field. The burden
+ // is placed on the VM thread, which must poll (spin).
+ // 2. Find something useful to do while spinning. If the safepoint is GC-related
+ // we might aggressively scan the stacks of threads that are already safe.
+ // 3. Use Solaris schedctl to examine the state of the still-running mutators.

- // Spin to avoid context switching.
- // There's a tension between allowing the mutators to run (and rendezvous)
- // vs spinning. As the VM thread spins, wasting cycles, it consumes CPU that
- // a mutator might otherwise use profitably to reach a safepoint. Excessive
- // spinning by the VM thread on a saturated system can increase rendezvous latency.
- // Blocking or yielding incur their own penalties in the form of context switching
- // and the resultant loss of $ residency.
- //
- // Further complicating matters is that yield() does not work as naively expected
- // on many platforms -- yield() does not guarantee that any other ready threads
- // will run. As such we revert to naked_short_sleep() after some number of iterations.
- // nakes_short_sleep() is implemented as a short unconditional sleep.
- // Typical operating systems round a "short" sleep period up to 10 msecs, so sleeping
- // can actually increase the time it takes the VM thread to detect that a system-wide
- // stop-the-world safepoint has been reached. In a pathological scenario such as that
- // described in CR6415670 the VMthread may sleep just before the mutator(s) become safe.
- // In that case the mutators will be stalled waiting for the safepoint to complete and the
- // the VMthread will be sleeping, waiting for the mutators to rendezvous. The VMthread
- // will eventually wake up and detect that all mutators are safe, at which point
- // we'll again make progress.
- //
- // Beware too that that the VMThread typically runs at elevated priority.
- // Its default priority is higher than the default mutator priority.
- // Obviously, this complicates spinning.
- //
- // Note too that on Windows XP SwitchThreadTo() has quite different behavior than Sleep(0).
- // Sleep(0) will _not yield to lower priority threads, while SwitchThreadTo() will.
- //
- // See the comments in synchronizer.cpp for additional remarks on spinning.
- //
- // In the future we might:
- // 1. Modify the safepoint scheme to avoid potentially unbounded spinning.
- // This is tricky as the path used by a thread exiting the JVM (say on
- // on JNI call-out) simply stores into its state field. The burden
- // is placed on the VM thread, which must poll (spin).
- // 2. Find something useful to do while spinning. If the safepoint is GC-related
- // we might aggressively scan the stacks of threads that are already safe.
- // 3. Use Solaris schedctl to examine the state of the still-running mutators.
- // If all the mutators are ONPROC there's no reason to sleep or yield.
- // 4. YieldTo() any still-running mutators that are ready but OFFPROC.
- // 5. Check system saturation. If the system is not fully saturated then
- // simply spin and avoid sleep/yield.

-Events in the JVM are by default timed (it's more common)
-Perhaps a little strange. Might change.
-
-EVENTS
-
-Declard with the 'event' tag.
-
-<value fields> can be one or more of
- value - a simple primitive or constant type value
- structvalue - value is a sub-struct. This type must be previously defined
- with 'struct'
-All these require you to declare type, field and label of the field. They also accept
-an optional description of the field. If the meaning of the field is not obvious
-from the label you should provide a description. If an event however is not actually
-meant for end-users, you should probably _not_ write descriptions at all, since you
-might just add more concepts the user has no notion of/interest in.
-
-Events should be modeled after what conceptual process you are expressing, _NOT_
-from whatever data structures you might use inside the JVM for expressing a process.
-
-
-STRUCT
-
-Declared with the 'struct' tag.
-
-Declares a structure type that can be used in other events.

+Events in the JVM are by default timed (it's more common)
+Perhaps a little strange. Might change.
+
+EVENTS
+
+Declard with the 'event' tag.
+
+<value fields> can be one or more of
+ value - a simple primitive or constant type value
+ structvalue - value is a sub-struct. This type must be previously defined
+ with 'struct'
+All these require you to declare type, field and label of the field. They also accept
+an optional description of the field. If the meaning of the field is not obvious
+from the label you should provide a description. If an event however is not actually
+meant for end-users, you should probably _not_ write descriptions at all, since you
+might just add more concepts the user has no notion of/interest in.
+
+Events should be modeled after what conceptual process you are expressing, _NOT_
+from whatever data structures you might use inside the JVM for expressing a process.
+
+
+STRUCT
+
+Declared with the 'struct' tag.

+Declares a structure type that can be used in other events.

/**
- * A program element annotated @Deprecated is one that programmers
- * are discouraged from using, typically because it is dangerous,
- * or because a better alternative exists. Compilers warn when a
- * deprecated program element is used or overridden in non-deprecated code.
+ * A program element annotated {@code @Deprecated} is one that programmers
+ * are discouraged from using. An element may be deprecated for any of several
+ * reasons, for example, its usage is likely to lead to errors; it may
+ * be changed incompatibly or removed in a future version; it has been
+ * superseded by a newer, usually preferable alternative; or it is obsolete.
+ *
+ * <p>Compilers issue warnings when a deprecated program element is used or
+ * overridden in non-deprecated code. Use of the {@code @Deprecated}
+ * annotation on a local variable declaration or on a parameter declaration
+ * or a package declaration has no effect on the warnings issued by a compiler.
+ *
+ * <p>This annotation type has a string-valued element {@code since}. The value
+ * of this element indicates the version in which the annotated program element
+ * was first deprecated.
*
- * <p>Use of the @Deprecated annotation on a local variable
- * declaration or on a parameter declaration or a package declaration
- * has no effect on the warnings issued by a compiler.
+ * <p>This annotation type has a boolean-valued element {@code forRemoval}.
+ * A value of {@code true} indicates intent to remove the annotated program
+ * element in a future version. A value of {@code false} indicates that use of
+ * the annotated program element is discouraged, but at the time the program
+ * element was annotated, there was no specific intent to remove it.
+ *
+ * @apiNote
+ * It is strongly recommended that the reason for deprecating a program element
+ * be explained in the documentation, using the {@code @deprecated}
+ * javadoc tag. The documentation should also suggest and link to a
+ * recommended replacement API, if applicable. A replacement API often
+ * has subtly different semantics, so such issues should be discussed as
+ * well.
+ *
+ * <p>It is recommended that a {@code since} value be provided with all newly
+ * annotated program elements. Note that {@code since} cannot be mandatory,
+ * as there are many existing annotations that lack this element value.

+ * Returns an out-of-bounds exception formatter from an given exception

+ *
+ * <p>The exception formatter accepts two arguments: a {@code String}

+ * out-of-bound integer values that failed the check. The list of
+ * out-of-bound values is not modified.
+ *
+ * <p>Three check kinds are supported {@code checkIndex},
+ * {@code checkFromToIndex} and {@code checkFromIndexSize} corresponding
+ * respectively to the specified application of an exception formatter as an
+ * argument to the out-of-bounds range check methods
+ * {@link #checkIndex(int, int, BiFunction) checkIndex},

+ * Thus a supported check kind corresponds to a method name and the
+ * out-of-bound integer values correspond to method argument values, in
+ * order, preceding the exception formatter argument (similar in many
+ * respects to the form of arguments required for a reflective invocation of
+ * such a range check method).
+ *
+ * <p>Formatter arguments conforming to such supported check kinds will
+ * produce specific exception messages describing failed out-of-bounds
+ * checks. Otherwise, more generic exception messages will be produced in
+ * any of the following cases: the check kind is supported but fewer
+ * or more out-of-bounds values are supplied, the check kind is not
+ * supported, the check kind is {@code null}, or the list of out-of-bound

+ *
+ * @apiNote
+ * This method produces an out-of-bounds exception formatter that can be
+ * passed as an argument to any of the supported out-of-bounds range check
+ * methods declared by {@code Objects}. For example, a formatter producing
+ * an {@code ArrayIndexOutOfBoundsException} may be produced and stored on a

+ * BiFunction<String, List<Integer>, ArrayIndexOutOfBoundsException> AIOOBEF =

+ * is within the bounds of a {@code limit}:
+ * <pre>{@code
+ * checkIndex(index, limit, AIOOBEF);
+ * }</pre>
+ * If the bounds check fails then the range check method will throw an
+ * {@code ArrayIndexOutOfBoundsException} with an appropriate exception

BUILDING
-To build a library, one should simply run make with 'JTREG_HOME' and
-'JAVA_HOME' environment variables set. 'JAVA_HOME' should contain path to JDK,
-'JTREG_HOME' -- path to jtreg.
-
-'image/lib/jtregFailureHandler.jar' is created on successful build.
+The library is built using the top level build-test-failure-handler target and
+is automatically included in the test image and picked up by hotspot and jdk
+test makefiles.
