[ https://issues.jboss.org/browse/WFCORE-3317?page=com.atlassian.jira.plugi... ] Marek Kopecký updated WFCORE-3317: ---------------------------------- Description: *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. Finalize method 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@67503391 rejected from java.util.concurrent.ThreadPoolExecutor@ae603d77[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0] at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2058) at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:834) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1380) at java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:145) at java.util.concurrent.Executors$DelegatedExecutorService.submit(Executors.java:692) at org.jboss.as.server.deployment.scanner.ShutdownFileSystemDeploymentServiceUnitTestCase.testUncleanShutdown(ShutdownFileSystemDeploymentServiceUnitTestCase.java:156) {noformat} *Actual results - FileSystemDeploymentServiceUnitTestCase:* StackTrace: {noformat} java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.FutureTask@9408464a rejected from java.util.concurrent.ThreadPoolExecutor@fa7bfba[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0] at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2058) at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:834) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1380) at java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:145) at java.util.concurrent.Executors$DelegatedExecutorService.submit(Executors.java:692) at org.jboss.as.server.deployment.scanner.FileSystemDeploymentServiceUnitTestCase.testUncleanShutdown(FileSystemDeploymentServiceUnitTestCase.java:1755) {noformat} *Expected results:* No errors was: *Description of problem:* Some deployment-scanner unit tests from wf-core fail on IBM JDK intermittently.
