+ * @summary converted from VM Testbase gc/gctests/WeakReference/weak002.
+ * VM Testbase keywords: [gc, stress, stressopt, nonconcurrent]
+ * VM Testbase readme:
+ * DESCRIPTION
+ *     The test checks that Garbage Collector correctly works with
+ *     WeakReferences. 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 test defines what type to check (there are 10 types
+ *     totally). As soon as the type is defined, a WeakReference is created that
+ *     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.
+ *     The test extends ThreadedGCTest and implements GarbageProducerAware and
+ *     MemoryStrategyAware interfaces. The corresponding javadoc documentation
+ *     for additional test configuration.
+ *
