32 * The test checks that Garbage Collector correctly works with
33 * SoftReferences. It also checks that no unexpected exceptions and errors
34 * are thrown or the JVM is not crashed.
35 * The test starts a number of threads. Each thread run tests for some time
36 * or serveral iterations. See javadoc StressOptions for configuration.
37 * First of all each thread defines what type to check (there are 10 types
38 * totally). As soon as the type is defined, a SoftRefence is created that
39 * refers to an array of tested type and is registered with in a queue. A
40 * SoftRefence for NonbranchyTree class does not refer to an array, but to
41 * instances of the class.
42 * After that a thread performs next checks for the reference:
43 * 1. The reference is in queue after GC is provoked with
44 * Algorithms.eatMemory() method (a single thread eats the memory).
45 * 2. queue.remove() returns reference from the queue.
46 * 3. queue.poll() returns null.
