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.
