+
+Here are tests that were developed for "G1 support for long running applications" feature. In effect,
+ here is only one test with a lot of configurations.
+
+Feature description:
+ G1 used to unload classes only during full collections. Goal of feature is to unload unused classes
+ without resorting to full gc.
+
+What does test checks:
+ - that unreferenced classloader will be collected without full gc. This is checked with WhiteBox.is
+ClassAlive method.
+ - that referenced classloader will live. This is checked with WhiteBox.isClassAlive method as well.
+ Also it is checked that classloader will be finalized and enqueued to queue of phantom references.
+
+In what aspects/circumstances checks performed:
+ - classloaders that we expect to be collected can be comlpetely unreferenced, referenced with phant
+om reference and with weak reference. Test can check that presence of phantom/weak reference doesn't
+keep classloader alive.
+ Test has flag "-referenceMode" that has valid options:
+ "phantom" for phantom reference,
+ "weak" for weak reference and
+ "none" for not keeping reference at all.
+ - to avoid class unloading we can keep reference to classloader itself, class or object.
+ This behavior can be adjusted with flag "-keep" that has valid options:
+ "classloader",
+ "class" and
+ "object".
+ - according to test plan several ways of classloading are covered.
+ This behavior is adjusted with "classloadingMethod" flag that has valid options
+ "plain",
+ "reflection",
+ "jni",
+ "anonymous_classloader".
+ - classloaders that we expect to live can be referenced in several ways.
+ This behavior can be adjusted with flag "-keepRefMode" that has valid options:
+ "strong_reference" for starighforward keeping strong reference,
+ "static_field" for keeping reference in static field of alive class,
+ "stack_local" for keeping reference in local variable of running thread,
+ "thread_field" for keeping reference in field of running thread's object,
+ "thread_itself" if we want object to be a running thread itself,
+ "static_field_of_root_class". In this case reference will be kept in static field of class that wa
+s loaded by null classloader.
+ "jni_global_ref". In this case global reference will be kept in native library.
+ "jni_local_ref", In this case local reference will be kept in JNI call in running thread.
+ - Another aspect is that class can be humongous.
+ Humongous classes can be enabled with "-humongousClass" command line option. Valid options are
+"true" and "false".
+ - Another aspect that is covered with tests is that class methods can be compiled by JIT compiler.
+ This behavior can be adjusted with "-compilationLevel" and "-compilationNumber" options. First
+one has self-explaining name, latter sets number of optimization/deoptimozation of each class.
+ - Next aspect is class redefinition.
+ You can enable classes redefinition with "-redefineClasses" flag.
+
+Test implementation details:
+ Test supposed to be ran with G1 gc and -XX:+ExplicitGCProvokesConcurrent option. In the end of exec
+ution test checks if full gc happened. If this is the case the test throws descriptive exception and
+fails.
+
+Test guts design:
+ Test in loop performs the following until time is over (timelimit is set up with "-stressTime" opti
+on):
+ - loads class that gonna live or gonna be unloaded. Decision depends upon Random.nextBoolean().
+ - previous action produces collection of Assertions (what assertion is is explained a little bit lat
+er). Assertions are saved into AssertionContainer.
+ - takes from AssertionContainer assertions that are already mature for check and performs checks. "M
+ature" means that required number of System.gc() calls happened since assertion was created.
+
+What "Assertion" is:
+ Assertion incapsulates check that concrete class will be alive or dead. Hazard is that we can't perf
+orm check just after we removed last reference to classloader. We have to wait some number of concurr
+ent-mark-cycles, i.e. System.gc() calls. For this reason we put each assertion in AssertionContainer
+and get back much later, when it's ready for check.
+ Classes of assertions form the following simple hierarchy:
+
+ gc.g1.unloading.check.Assertion
+ || || ||
+ \/ || \/
+ gc.g1.unloading.check.FinalizedAssertion || gc.g1.unloading.check.PhantomizedAssertion
+ \/
+ gc.g1.unloading.check.ClassAssertion
+
+FinalizedAssertion checks that unreferenced classloader will be finalized.
+PhantomizedAssertion checks that phantom reference to classloader will be enqueued to ReferenceQueue.
+ClassAssertion checks that class will be dead or alive using WhiteBox.isClassAlive method.
+
+Other implemention notes:
+ There are some other auxiliary threads, but they are not crucial for understanding the logic.
+ There are a lot of configurations of the same test in testlist. All configurations use the same mai
+n method as entry point, but impose different test flags. Configurations are autogenerated with "gene
+rate.sh" script.
+
+Other test options:
+ -DFailTestIfNothingChecked=true. (vm flag) Set this if you want test to fail if nothing was checked
+and test appeared to be useless. It can happen, for example, in slow modes that force compilation.
+ -numberOfChecksLimit. (test flag) Set this number if you want test to pass after certain number of c
+hecks performed. (Not to waste time.) To some extent this turns stress test into functional test.
+ -numberOfGCsBeforeCheck. (test flag) This option sets number of System.gc() calls that have to be do
+ne before each assertion will be ready to perform checks.
+ -inMemoryCompilation. (test flag) This option defines the way of classes creation. If this is true t
+hen classes are compiled with javac API. If false - classes are produced by rewriting classname in "g
+olden" bytecode.

+ * This test is a slightly modified version of a test taken from a research paper
+ * by CE McDowell of UCSC titled 'No so static "static fields"'.
+ * To quote from the paper :
+ * " In this paper we have identified a problem with the Java Language
+ * Specification with regard to class unloading and static fields. We have
+ * provided an example that demonstrates how the current implementation of
+ * class unloading can result in a static field being reinitialized resulting
+ * in a program that changes its behavior depending upon when garbage collection occurs."
+ * In this test, the creation of the object first assigned to
+ * class_one_object (actually an instance of ClassOne) also creates an instance
+ * of ClassTwo which contains a static field. Once the references to the ClassOne
+ * object and the Class object are set to null, a call to the garbage
+ * collector results in both ClassOne and ClassTwo being unloaded. When
+ * the final assignment to class_one_object occurs, creating a new instance of ClassOne
+ * and a new instance of ClassTwo, the program should print out the value of counter in
+ * ClassTwo as 2. This would mean that class was not unloaded and the static field
+ * was not reinitialized. If the test prints out 1, the test has failed as the static
+ * field was reinitilized.

+ * DESCRIPTION
+ * The test checks that Garbage Collector can manage jumble in the JVM. The
+ * test fails if any unexpected exceptions and errors are thrown or the JVM
+ * is not crashed.
+ * The test starts a number of threads that is set in *.cfg file or calculates
+ * that value based on the machine. All threads have
+ * java.util.Vector field anf they fill that vector with 4 types of objects:
+ * 1. Initialized long[]
+ * 2. Uninitialized double[]
+ * 3. Initialized int[]
+ * 4. A nsk.share.gc.NonbranchyTree (number of nodes and their size depend
+ * on valkue returned by Runtime.maxMemory())
+ * As soon as the vector is filled, each thread removes half elements of it and
+ * then fills those places of the vector again. However, all threads use just
+ * about 10% of maximum amount of memory that JVM attemts to use, so
+ * OutOfMemoryError is treated as a failure. That means GC does not work
+ * quickly enough to destroy all objects that do not have references. The
+ * procedure of filling and cleaning of the vector is repeated for
+ * INTERNAL_ITERATIONS times.

+ * VM Testbase keywords: [gc, stress, stressopt, nonconcurrent, quick]
+ * VM Testbase readme:
+ * DESCRIPTION
+ * The test checks that Garbage Collector correctly does not throw any
+ * unexpected exceptions/errors while allocating large objects (classes
+ * that have more than 65535 fields and classes that have less than 65535
+ * fields). 65535 of fields is a limitation for JVM (see JVM specification
+ * Second edition 4.10).
+ * Since it is impossible to create one class with about 65535 of fields
+ * (javac cannot compile it), a child class extends a parent class, so the
+ * fields are devided into two subsets. However, the child class still has
+ * about 65535 of fields.
+ * The test starts a number of threads. This number is either set in *.cfg
+ * file or is calculated by the test itself based on the machine (see
+ * nsk.share.gc.Algorithms.getThreadsCount() method). As soon as all threads
+ * are started, each thread begins its checking.
+ * There are 13 classes to be loaded by each thread. These classes are
+ * generated by nsk.share.gc.Generator (see its javadoc for more details).
+ * Each class has a huge number of fields, but this number is less than the JVM
+ * limitation.
+ * The test loads the classes with nsk.share.gc.GCClassUnloader class that
+ * extends nsk.share.ClassUnloader and has a bit different algorith of eating
+ * heap. As soon as a class is loaded, the test creates an instance of
+ * it - allocates an object of that type. Then it drops references to the
+ * class and to the instance and tries to unload the class. The test does not
+ * expect any exceptions to be thrown.

+ * The test checks that Garbage Collector correctly does not throw any

+ * that have more than 65535 fields and classes that have less than 65535
+ * fields). 65535 of fields is a limitation for JVM (see JVM specification

+ * (javac cannot compile it), a child class extends a parent class, so the
+ * fields are devided into two subsets. However, the child class still has
+ * about 65535 of fields.
+ * The test starts a number of threads. This number is either set in *.cfg

+ * nsk.share.gc.Algorithms.getThreadsCount() method). As soon as all threads
+ * are started, each thread begins its checking.
+ * There are 13 classes to be loaded by each thread. These classes are
+ * generated by nsk.share.gc.Generator (see its javadoc for more details).
+ * Each class has a huge number of fields, but this number is less than the JVM
+ * limitation.
+ * The test loads the classes with nsk.share.gc.GCClassUnloader class that
+ * extends nsk.share.ClassUnloader and has a bit different algorith of eating
+ * heap. As soon as a class is loaded, the test creates an instance of
+ * it - allocates an object of that type. Then it drops references to the

+ * expect any exceptions to be thrown.
+ * Additionaly to original tests this test create object with large count of

+ * ********************************
+ * set TIMEOUT = 20
+ * *******************************
+ * This test creates a 2 dimensional matrix of (100X100)10,000 elements.
+ * Each element in this matrix houses the address of a "Cell" that
+ * occupies about 100 bytes. The total memory occupied by this structure is
+ * about 1M.
+ * Once this structure, has been built, 5 threads are let loose that
+ * randomly choose an element in this matrix and set its contents to null
+ * effectively creating 100bytes of garbage. The threads continue to act
+ * until all 5 threads combined have "nulled out" half the cells in the matrix.
+ * At this point, 5 refiller threads proceed to refill the empty
+ * matrix elements with new cells.
+ * Once the refiller threads have refilled all the empty matrix elements
+ * with new cells, the cycle begins all over again with the 5 "emptier"
+ * threads "nulling out" cells randomly.
+ * This is repeated 50 times. Every iteration produces 0.5 Meg
+ * of garbage. The maximum amount of live memory at use at any time is 1Meg.
+ * If no garbage collection takes place during any of the ten iterations,
+ * the total amount(live + garbage) of heap space consumed at the end
+ * of the program is 0.5*50 + 1 = 26Meg.
+ * The test fails if an OutOfMemory Exception is thrown.

+ * The test starts a number of threads. Each thread run tests for some time

+ * refers to an array of tested type and is registered with in a queue. A
+ * PhantomRefence for NonbranchyTree and Referent calsses does not refer to
+ * arrays, but to instances of the classes.
+ * After that a thread performs next checks for the reference:
+ * 1. The reference is in queue after GC is provoked with
+ * Algorithms.eatMemory() method (a single thread eats the memory).
+ * 2. reference.get() returns null.
+ * 3. queue.poll() returns the reference that was created.
+ * 4. queue.poll() again returns null.
+ * 5. If the checked type is class (Referent), then it must be finalized,
+ * since the reference is already enqueued.

+ * DESCRIPTION
+ * The test checks that Garbage Collector correctly works with
+ * SoftReferences. It also checks that no unexpected exceptions and errors
+ * are thrown or the JVM is not crashed.
+ * The test starts a number of threads. Each thread run tests for some time
+ * or serveral iterations. See javadoc StressOptions for configuration.
+ * First of all each thread defines what type to check (there are 10 types
+ * totally). As soon as the type is defined, a SoftRefence is created that
+ * refers to an array of tested type and is registered with in a queue. A
+ * SoftRefence for NonbranchyTree class does not refer to an array, but to
+ * instances of the class.
+ * After that a thread performs next checks for the reference:
+ * 1. The reference is in queue after GC is provoked with
+ * Algorithms.eatMemory() method (a single thread eats the memory).
+ * 2. queue.remove() returns reference from the queue.
+ * 3. queue.poll() returns null.
+ * 4. reference.clear() does not throw any exception.
+ * The test extends ThreadedGCTest and implements GarbageProducerAware and

+ * refers to an array of tested type and is registered with in a queue. A
+ * WeakReference for NonbranchyTree class does not refer to an array, but to
+ * instances of the class.
+ * After that a thread performs next checks for the reference:
+ * 1. The reference is in queue after GC is provoked with
+ * Algorithms.eatMemory() method (a single thread eats the memory).
+ * 2. queue.remove() returns reference from the queue.
+ * 3. queue.poll() returns null.
+ * 4. reference.clear() does not throw any exception.

+ * set timeout = 25 when running this test
+ * *******************************************
+ * This tests checks to see if the garbage collector enqueues
+ * a weak reference when referrent has been turned to garbage.
+ * Weak references are enqueued in a non-deterministic way
+ * by the garbage collector, so the test uses a heuristic to
+ * determine whether the references are being enqueued in a timely
+ * manner which in turn determines whether outcome of the test.
+ * IF the user invokes the test with the following command line
+ * parameters :
+ * java WeakReferenceGC -qFactor 0.9 -gcCount 5
+ * the test expects that 90% of all objects with only weak references
+ * pointing to them will be enqueued within 5 calls to the garbage collector.
+ * When I ran the test, I consistently got figures of 98% enqueueing
+ * with just 1 call to the garbage collector. So if this test fails,
+ * at its current settings, the garbage collector is not performing as well
+ * as it used to.
+ * The test creates circular linked lists of size 0.1Meg each. The number
+ * of lists created can be set via the -numLists flag. The default
+ * value is 50.
+ * The circular linked lists have both strong and weak references pointing
+ * to them. The strong and weak references are kept in arrays.
+ * The strong references are all nulled out and System.gc() is called
+ * explicitly and the heuristic is applied. If the test does not
+ * satisfy the heuristic or an OutOfMemory exception is thrown,
+ * the test fails.
+ * Array containing Each circular linked list Array containing
+ * weak references is 0.1 Meg each and has strong references
+ * to linked lists. a weak reference, W<n> and a to linked lists.

+ * This test creates a 2 dimensional matrix of (100X100)10,000 elements.
+ * Each element in this matrix houses the address of a "Cell" that
+ * occupies about 100 bytes. The total memory occupied by this structure is
+ * about 1M.
+ * Once this structure, has been built, 5 threads are let loose that
+ * randomly choose an element in this matrix and set its contents to null
+ * effectively creating 100bytes of garbage. The threads continue to act
+ * until all 5 threads combined have "nulled out" half the cells in the matrix,
+ * which amounts to 0.5Meg of garbage. The indices of each "nulled out"
+ * cell is stored in a stack. This information is later used during
+ * the refilling stage by the native function, kickOffRefiller();
+ * The native function, kickOffRefiller() refills all the lacunae in the
+ * matrix with new cells.
+ * This process of nulling out" and refilling is repeated 50 times.
+ * Every iteration produces 0.5 Meg
+ * of garbage. The maximum amount of live memory at use at any time is 1Meg.
+ * If no garbage collection takes place during any of the ten iterations,
+ * the total amount(live + garbage) of heap space consumed at the end
+ * of the program is 0.5*50 + 1 = 26Meg.
+ * The test fails if an OutOfMemory Exception is thrown.

+ * The approach is to nearly simultaneously lock/hash a relatively small group

+ * DESCRIPTION
+ * The test is intended to test 64-bit VM for large memory and heap
+ * functionalities. This test checks that no unexpected exceptions and errors
+ * are thrown or the JVM is not crashed during allocation of different
+ * objects within 32-bit address range.
+ * First of all the test checks that the maximum amount of memory that
+ * the Java virtual machine will attempt to use (Runtime.maxMemory()) is
+ * greater than 4G. If that value is less than 4G, the test passes, otherwise
+ * it starts testing.
+ * A number of threads is started. That number is set in *.cfg file or is
+ * calculated by the test itself based on the machine (see
+ * nsk.share.gc.Algorithms.getThreadsCount() method).
+ * Each thread creates 9 arrays - one of each of the following types: byte,
+ * short, char, int, long, boolean, double, float, Object. All arrays have
+ * the same size, and that size is calculated so that all threads together are
+ * supposed to eat about 1.3G of the heap (30% of 4G).

+
+All gc/lock/ tests do approximately the same thing. They verify that GC
+is appropriately synchronized with certain class of functions.
+
+- gc/lock/jni - uses JNI GetPrimitiveArrayCritical and GetStringCritical
+- gc/lock/jniref - uses JNI NewGlobalRef, NewLocalRef, NewWeakGlobalRef
+- gc/lock/malloc - uses malloc()
+- gc/lock/jvmti - uses JVMTI Allocate
+
+A number of threads is started. There are some threads that repeatedly
+enter a critical section of code where functions describe above are
+repeatedly called in a loop. There are also some threads that eat
+memory in a loop. The idea here is to force GC to crash or deadlock.

+
+ArrayJuggle.README
+
+These are a series of tests to exercise the multi-threaded
+GC part of the JVM.
+
+MemoryObjects are objects with a byte array to control their
+size and next and previous pointers for building up links to
+other MemoryObjects. These pointers can be used to make linked
+lists or binary trees or whatever. In these test cases, they are
+used only to build singly-linked lists.
+
+In the main class for each ArrayJuggle test, there is an array of
+MemoryObjects called the mainArray. This array is acted upon
+by various threads.
+
+MainArrayWalker threads randomly pick a cell in the main array
+and allocate a new MemoryObject into it. This means that
+the previous occupant of this cell in the array and anything
+it points to are candidates for GC.
+
+The CopyingThread threads copy parts of the main array into
+a thread-local array. While it resides in the thread-local array,
+a MemoryObject and the objects it points to should not be GC'd.
+
+The LinkMaker threads add new objects at the head of a linked
+list. The head of the list is stored in the main array. These
+links can vary in size.
+
+In Juggle1, a single CopyingThread copies the values of the main array to the
+subarray, a single LinkMaker adds nodes to the main array, and a single
+MainArrayWalker turns over the main array.
+
+Juggle2 is the same as Juggle1, but the CopyingThread puts a reference
+to the main array cell in the thread-local sub-array instead of
+copying it. A small difference.
+
+Juggle3 is the same as Juggle1, but is configurable for how many
+of each type of thread exists.
+
+Juggle4 is the same as Juggle2, but also has arrays of threads which
+operate on the array.
+
+The "gc" versions of these tests all have one or more threads
+which simply sit in a loop calling System.gc() to stress the system.
+
+
+These programs are designed to have their values adjusted to stress
+different parts of the system. A simple command interface can be
+added to adjust these at runtime, or the files can be edited and
+recompiled.
+
+No attempt has been made to synchronize access to the various array
+structures. This means that the arrays at any given moment inside
+any given thread may not necessarily be consistent. This is by
+design.
+
+Because there is no synchronization across array accesses, the
+values given by the dumpStatistics will not be precise, but will
+instead reflect a rolling average.
+
+Currently, all these programs run forever. That is because the
+curernt 1.1E system eventually fails on these tests. Each of
+the threads has a mechanism for stopping. The main program can
+wait for some specified period of time or number of iterations
+and then set runForever = false on all its child threads and
+then join() on them and the program should eventually terminate.
+This will be necessary for adding these to VM Testbase.
+
+Also, it will be interesting to run these tests in multiple
+configurations (varying the number of mutator threads) to
+help check for problems.

+
+The Churn tests are a series of small programs designed to
+simply churn memory over, mixing in calls to GC and Finalization.
+They are all basically the same program with permutations.
+Each program contains:
+
+LocalRandom class -- used to isloate calls to random generator
+ for reproducibility
+
+MemoryObject class -- simply allocated and reclaimed. contains
+ a byte array
+
+Churn class -- entry point. Allocates threads and counts objects.
+ When loop is done, sets Semaphore to signal threads to cease
+
+ThreadObject class -- allocates and deallocates (by assignment)
+ MemoryObjects
+
+SemaphoreObject class -- static class for signalling threads when
+ to stop running. Perhap poorly named.
+
+CommandLine class -- parses command line args. Static class.
+--------------------------
+Usage:
+
+java Churn [-l numberOfLoops] [-t numberOfThreads] [-a sizeOfArray] [-m multiplier] [-f <run forever>] [-s seed]
+
+NOTE: the options can be passed in any order
+
+
+seed is the seed for the LocalRandom pseudo-random generator
+
+numberOfLoops is the number of iterations a test will go through.
+This defaults to 2000
+
+numberOfThreads is the number of threads activating and deactivating
+MemoryObjects. This deaults to 2.
+
+sizeOfArray is the number of MemoryObjects each thread manipulates.
+This defaults to 1024.
+
+multiplier is a value used to determine how much memory each MemoryObject
+holds. It defaults to 10.
+
+The tests can be configured to run forever by passing -f on the
+command line. This is useful for continued stress testing outside
+of a test harness.
+-----------------------------
+The total amount of needed memory is approximately
+numberOfThreads * (sizeOfArray * sizeOfArray) * (multiplier / 2) bytes
+
+The default is about 10 Megs needed, not couting garbage collection
+overhead. Garbage collection doubles the memory requirements for
+programs that run out of heap space, so the the true default size
+is 20 Megs.
+
+
+Testname What it does
+------------- ---------------------------------------------------------
+Churn1 Simply creates new MemObjects. No finalizers. No user
+ calls to System.gc(). Count of objects simply grows
+ since no method ever decreases the count -- object count
+ equals total objects ever allocated. Memory used is
+ approx = (object count) * (array size) * (multiplier) / 2
+
+Churn2 Same as Churn1, but adds a call to System.gc() every loop.
+ Object Count should simply increase. About half the time,
+ this test will hang before the 100th loop. About 10% of
+ the time this test will SEG FAULT with either a BUS ERROR
+ or ACCESS VIOLATION
+
+Churn3 Same as Churn1, but the MemoryObject class has a
+ finalize() method on it. The method is empty. The objecty
+ count should continue to rise. However, this program
+ runs out of memory after around 35 loops. The threads
+ dies from OutOfMemoryErrors. It looks as if the
+ finalizers are not called fast enough during GC, so
+ enough memory cannot be freed.
+ Additionally, about 10% of the time, this program SEGFAULTS
+
+Churn3a Same as Churn3, but with an explicit call to
+ System.runFinalization() in each loop.
+ Occasionally, this test will run out of memory
+ early on for one or more of the threads.
+ Also, this test sometimes hangs, even if one or
+ all of the ThreadObjects have died.
+ Even if no threads die, and it doesn't hang, this
+ program will still die with:
+ java.lang.NullPointerException
+ at java.lang.String.indexOf(String.java)
+ at Churn3a.main(Churn3a.java:71)
+ which contains only a call to join()
+
+
+
+Churn4 Same as Churn3, but with code in the finalize method
+ which would decrement a *static* field in the class.
+ This test runs out of memory much more quickly, something
+ like after 3 or 4 loops.

+
+The Unithread Circular tests are pretty basic.
+The main program allocates an array of objects and
+the generates a circular linked list from them.
+ A->B->C->A
+The circularity is then removed from the array
+as more objects are allocated. The circularities
+should be garbage collected to make room for the new
+obects.
+
+Circular1 uses 5000 objects of 100 bytes (or so) apiece
+in chains of 5 objects apiece in a singly-linked list.
+
+Circular2 uses 10000 objects of 1000 bytes (or so) apiece
+in chains of 100 objects apiece.
+
+Circular3 is the same as Circular1, but uses a local
+Random Number Generator to access the arrays in a non-linear
+way.
+
+Circular4 is the same as Circular2, but uses a local
+Random Number Generator to access the arrays in a non-linear
+way.

+The Unithread Linear tests are pretty basic.
+The main program allocates an array of objects and
+the generates a linked list from them.
+ A->B->C->D
+The list is then removed from the array
+as more objects are allocated. The lists
+should be garbage collected to make room for the new
+obects.
+
+Linear1 uses 5000 objects of 100 bytes (or so) apiece
+in chains of 5 objects apiece in a singly-linked list.o
+
+Linear2 uses 10000 objects of 1000 bytes (or so) apiece
+in chains of 100 objects apiece.
+
+Linear3 is the same as Linear1 but uses a local random number
+generator to access the arrays in a non-linear way;
+
+Linear4 is the same as Linear2 but uses a local random number
+generator to access the arrays in a non-linear way;

+Simple garbage collection tests test that GC is able to collect simple objects.
+The test executes the following for several iterations: create array of objects,
+then null all references and refill the array with new objects. The test uses
+notions of garbage producer (nsk.share.gc.gp.GarbageProducer) and memory strategy
+(nsk.share.gc.gp.MemoryStrategy) to alter it's behaviour. The tests automatically
+adjust parameters to memory available to JVM as returned by Runtime.maxMemory().
+Tests with "high" memory strategy (*High) create small number of big objects,
+tests with "low" memory strategy (*Low) create huge number of small objects.

+Test garbage collector compaction.
+
+The test starts several threads which create objects using
+given garbage producer until OOM. The references are kept
+in an array. The references to even elements are cleared
+and objects of double size are created until OOM. The garbage
+collector will have to compact free space to free memory for
+new objects.
+
+The tests differ by object types used for first and second phase:
+- _Arrays tests randomly use arrays of basic types and Object[] arrays.
+- _Strings tests use random strings.
+- _NonbranchyTree tests use nonbranchy trees.
+- _InternedStrings use interned strings.
+- _ArrayOf tests use array with two elements for second phase,
+the elements of which point to objects of same type.
+- _TwoFields tests use object with two fields for second phase,
+which point to objects of same type.
+
+Each *1 test is the single-threaded version of corresponding test.
+
+The Humongous tests are similar to compact tests. However they used
+the fixed size of objects which allocation requre compaction. The
+size is specific for G1 GC (about 1M and 5M) and require humongous
+object creation in G1.
