[jira] [Created] (FLINK-6050) Improve failure reporting when using Future.thenAccept

Till Rohrmann created FLINK-6050:
------------------------------------

             Summary: Improve failure reporting when using Future.thenAccept
                 Key: FLINK-6050
                 URL: https://issues.apache.org/jira/browse/FLINK-6050
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.3.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
            Priority: Minor


When applying {{Future.thenAccept(Async)}} onto a {{Future}}, then we should register the exception handler on the returned {{Future<Void>}} and not on the original future. This has the advantage that we also catch exceptions which are thrown in the {{AcceptFunction}} and not only those originating from the original {{Future}}. This improve Flink's behaviour, because exceptions are not swallowed in the returned {{Future}}.
