[infinispan-issues] [JBoss JIRA] (ISPN-2717) execute(Runnable) of DistributedExecutorService doesn't show exception message in case of failure of Runnable

[Anna Manukyan (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-2717?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Anna Manukyan updated ISPN-2717:
--------------------------------

    Description: 
Assume, that we have a runnable which run() method throws RuntimeException.

In case if the runnable is executed using void execute(Runnable command) for DistributedExecutorService, the execution of runnable fails - but there is no any stacktrace printed in the logs.

So it is really hard to find, what was wrong in your Runnable.

The sample test which does this is:

{code}
public void testRunnableExecution() throws InterruptedException {
      //assuming cache initialization is done
      DistributedExecutorService des = new DefaultExecutorService(cache);
      SampleRunnable runnable = new SampleRunnable();

      des.execute(runnable);
   }

static class SampleRunnable implements Runnable, Serializable {

      public SampleRunnable() {
      }

      @Override
      public void run() {
         System.out.println("Running runnable");
         int i = 5 / 0;
      }
   }
{code}
