/* This test is used to test jdb reporting wrong thread status information
   Steps to reproduce the problem:
     jdb FooTest
     stop at FooTest:53 - the last line in changeVarOne()
     run
     cont - a few times
     threads

   All but one of Thread-0 through Thread-9 should be "waiting on a
   monitor". But jdb reports more more than one threads "running". If you do a
   where <thread id> on the running threads, you will see they are actually
   waiting to enter the synchornized method. It seemed like once a thread has
   been marked as running, jdb will always think it's a running thread even.
