[infinispan-issues] [JBoss JIRA] (ISPN-2451) DefaultExecutorService invokeAny(Collection tasks, long timeout, TimeUnit unit) does not timeout

DefaultExecutorService invokeAny(Collection tasks, long timeout, TimeUnit unit) does not timeout ------------------------------------------------------------------------------------------------ Key: ISPN-2451 URL: https://issues.jboss.org/browse/ISPN-2451 Project: Infinispan Issue Type: Bug Components: Distributed Execution and Map/Reduce Affects Versions: 5.1.8.Final Reporter: Anna Manukyan Assignee: Vladimir Blagojevic Fix For: 5.2.0.CR1, 5.2.0.Final Attachments: DistributedExecutorTest.java Hi, I've written some new tests for DefaultExecutorService for both testing the product as well as for increasing the coverage and I have some strange behaviour which I don't know whether related to concurency non-reliability or it is a bug. I have a Callable which just sleeps for 10 seconds and the returns 1. And I have a test, which submits the callable to DefaultExecutorService with invokeAny(collection, timeout, TimeUnit) method, and passes as a parameter to the method 2 seconds. As far as I understand, this means that if the execution of any of the tasks will not complete in 2 seconds, the Timeout exception should be thrown. But everytime I run the test, the TimeoutException is thrown only once maybe in 5 executions. The exception is: org.testng.TestException: Expected exception java.util.concurrent.TimeoutException but got org.testng.TestException: Method org.infinispan.distexec.DistributedExecutorTest.testInvokeAnyTimedSleepingTasks() should have thrown an exception of class java.util.concurrent.TimeoutException at org.testng.internal.Invoker.handleInvocationResults(Invoker.java:1416) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1184) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:125) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:109) at org.testng.TestRunner.runWorkers(TestRunner.java:1147) at org.testng.TestRunner.privateRun(TestRunner.java:749) at org.testng.TestRunner.run(TestRunner.java:600) at org.testng.SuiteRunner.runTest(SuiteRunner.java:317) at org.testng.SuiteRunner.access$000(SuiteRunner.java:34) at org.testng.SuiteRunner$SuiteWorker.run(SuiteRunner.java:351) at org.testng.internal.thread.ThreadUtil$CountDownLatchedRunnable.run(ThreadUtil.java:147) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) Caused by: org.testng.TestException: Method org.infinispan.distexec.DistributedExecutorTest.testInvokeAnyTimedSleepingTasks() should have thrown an exception of class java.util.concurrent.TimeoutException at org.testng.internal.Invoker.handleInvocationResults(Invoker.java:1442) at org.testng.internal.Invoker.invokeMethod(Invoker.java:722) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:846) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1170) ... 12 more You can find the test attached, the test case is: testInvokeAnyTimedSleepingTasks() .
