* VM Testbase keywords: [quick, jpda, jdi, feature_jdk6_jpda, vm6]
* VM Testbase readme:
* DESCRIPTION
* This scenario in particular cover the situation described in CR 6376715.
* The test scenario is following:
* - the debugger gets the debuggee running on another JavaVM and
* establishes a pipe with the debuggee program
* - upon receiving corresponding command from the debugger process the debuggee
* loads set of classes and creates the number of class instances
* - the debugger process check that instanceCounts returns correct number
* - the debuggee process deletes previously created objects(make them unreachable) and
* enforces GC to clean up the heap.
* - the debugger process checks that instanceCounts returns 0 and no
* com.sun.jdi.ObjectCollectedException is thrown
*
* @requires !vm.graal.enabled
