* @summary converted from VM Testbase nsk/jdi/VirtualMachine/instanceCounts/instancecounts004.
* VM Testbase keywords: [quick, jpda, jdi, feature_jdk6_jpda, vm6]
* VM Testbase readme:
* DESCRIPTION
* This is stress test against method "VirtualMachine.instanceCounts()".
* Test scenario:
* - Repeat the following steps 3 times:
* - Debuggee VM: create the number of different objects to consume 30% of available memory
* - Debuggee VM: create new thread 'GCProvocateur' which will try to consume the rest of memory to provoke GC
* - Debugger VM: at the same time call VirtualMachine.instanceCounts(VirtualMachine.allClasses()) 10 times
* - Debuggee VM: stop 'GCProvocateur' thread
* Test is treated as passed if no any unexpected events was caught during test execution and debuggee VM doesn't crash.
*
