 * @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
