> 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
