             Summary: Multiple ExecutorAllCompletionServices using the same executor may interfere
                 Key: ISPN-3800
                 URL: https://issues.jboss.org/browse/ISPN-3800
             Project: Infinispan
          Issue Type: Bug
    Affects Versions: 6.0.0.Final
            Reporter: Radim Vansa
            Assignee: Radim Vansa


If there are multiple ExecutorAllCompletionServices using the same executor, these may steal other's futures, and therefore, report the task to be finished prematurely.

This may be the case for a preload from multiple cache loaders in parallel.

The tasks sent to the executor have to be tagged and the service should poll only its own tasks.
