> *Description of problem:*
> Some deployment-scanner unit tests from wf-core fail on IBM JDK intermittently.
> This is testsuite issue only.
> Affected test cases:
> * ShutdownFileSystemDeploymentServiceUnitTestCase
> * FileSystemDeploymentServiceUnitTestCase
> Executors.newSingleThreadExecutor() method returns ExecutorService with finalize method, that shutdown thread executor. Currently ExecutorService instance is not referenced, so IBM JDK calls finalize method. It calls shutdown method and size of thread-pool is decreased to 0 before lockDone.get(...) is called.
> *How reproducible:*
> 0.6% - intermittently on IBM JDK
> *Actual results - ShutdownFileSystemDeploymentServiceUnitTestCase:*
> StackTrace:
> {noformat}
> java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.FutureTask at 67503391 rejected from java.util.concurrent.ThreadPoolExecutor at ae603d77[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0]
