* @test
*
* @summary converted from VM Testbase nsk/jdi/EventRequestManager/createStepRequest/crstepreq004.
* VM Testbase keywords: [jpda, jdi]
* VM Testbase readme:
* DESCRIPTION:
* The test checks whether an implementation of
* EventRequestManager.createStepRequest (ThreadReference thread, int size, int depth)
* method complies with its spec.
* The test checks the following assertions:
* A size value of StepRequest.STEP_LINE will generate a step event each time
* the source line changes. A depth value of StepRequest.STEP_INTO will generate
* step events in any called methods. A depth value of StepRequest.STEP_OVER
* restricts step events to the current frame or caller frames. A depth value
* of StepRequest.STEP_OUT restricts step events to caller frames only.
* The debugger class - nsk.jdi.EventRequestManager.createStepRequest.crstepreq004;
* the debuggee class - nsk.jdi.EventRequestManager.createStepRequest.crstepreq004a;
* The test works as follows. At first, preliminary phase:
* - the debugger connects to the debuggee using nsk.jdi.share classes;
* - the debugger waits for the VMStartEvent and requested ClassPrepareEvent for
* debuggee class.
* At second, test specific phase, each action is performed for every test case:
* - the debugger waits for requested BreakpointEvent which is set on a line
* of debuggee's methodForCommunication() method;
* - the debuggee starts two threads, thread1 and thread2. Each of them must hold
* the lock of lockObj1 object inside its run() method.Thread1 is first one who
* captures the lock, thread2 waits at beginning of synchronized block.
* The debuggee's main thread invokes methodForCommunication() method at this moment;
* - After getting BreakpointEvent, the debugger sets StepRequest for thread2 and
* resumes debuggee;
* - after getting StepEvent, the debugger checks its location by comparing with
* expected line number value.
* There are three cases in the test:
* - step request is created with STEP_LINE size and STEP_INTO depth,
* - step request is created with STEP_LINE size and STEP_OVER depth,
* - step request is created with STEP_LINE size and STEP_OUT depth.
* In case of error the test produces the return value 97 and a corresponding
* error message(s). Otherwise, the test is passed and produces the return
* value 95 and no message.
* COMMENTS:
* This test is developed basing on analysis of 4628003 bug. The test is aimed
* to check to the case when debuggee's thread in step request is waiting for
* lock release in syncronized block which is held by another thread.
* Test was fixed according to test bug:
* 4778296 TEST_BUG: debuggee VM intemittently hangs after resuming
* - remove waiting for VMStartEvent after launching debuggee VM
