-----------------------------------

             Summary: ProducerFailedException does not properly preserve Exception causes
                 Key: FLINK-4566
                 URL: https://issues.apache.org/jira/browse/FLINK-4566
             Project: Flink
          Issue Type: Bug
          Components: Network
    Affects Versions: 1.1.2
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.2.0, 1.1.3


To avoid class loading issues with user-scope exceptions, the {{ProducerFailedException}} does not properly store its cause, but only a stringified variant of it.

We should use the {{SerializedThrowable}} instead of manual cause stringification.
