      Failing on all platforms.

      ## ERROR: ##> debugger: ERROR: timeout for waiting for a BreakpintEvent
      ## ERROR: TEST FAILED



      Name: dkR10014 Date: 01/29/2002



      The test fails only when debuggee class (issuspended002a class) is running
      on Client VM in -Xcomp mode. The test passes in other modes including when
      debuggee is running on Server VM in -Xcomp mode.
      The failure is observed on Solaris sparc 5.7, Solaris x86 5.8,
      Linux RedHat 6.2, Windows NT 4.0.

      The test checks that results of the method
       com.sun.jdi.ThreadReference.isSuspended()
      complies with its spec.

      The test checks a case when new thread (thread2) beside main one is created
      in debuggee and if thread2.isSuspended() is correct for various suspend
      count.
       
      Please see detailed description of test case algorithm in header comment
      of issuspended002.java file.

      The test fails because the expected Breakpoint event is not received in
      debugger. This event should be reported for Breakpoint request been set up
      for line in method exclusively invoked in thread2 after resuming.

      Below is part of test log demonstrating the failure:

      --> debugger: double resuming thread2 with thread2.resume();
      --> debugger: thread2.suspendCount() == 1
      --> debugger: : thread2.isSuspended()
      --> debugger: enabling breakpRequest1
      --> debugger: thread2.suspendCount() == 0
      --> debugger: : !thread2.isAtBreakpoint() before call to breakpoint()
      --> debugger: waiting for BreakpointEvent
      --> debugger: new: eventSet = eventQueue.remove();
      --> debugger: : eventSet != null; size == 1
      --> debugger: VMStartEvent removed
      --> debugger: new: eventSet = eventQueue.remove();
      # ERROR: ##> debugger: ERROR: timeout for waiting for a BreakpintEvent
      --> debugger: resuming both second and main thread
      debugee.stderr> **> thread2: entered into block: synchronized (lockingObject)
      debugee.stderr> **> thread2: exited from block: synchronized (lockingObject)
      debugee.stderr> **> thread2: call to the method 'runt1'
      debugee.stderr> **> thread2: method 'runt1' enter
      --> debugger: the end of testing


      To reproduce bug run script in
       /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/4628004 directory:

        sh doit.sh <JAVA_HOME> -client -Xcomp

       where "-client -Xcomp" are optional parameters for debuggee VM mode.
