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

             Summary: JulHandlerPrintStream failing to buffer carry over bytes
                 Key: BEAM-14539
                 URL: https://issues.apache.org/jira/browse/BEAM-14539
             Project: Beam
          Issue Type: Bug
          Components: runner-dataflow
    Affects Versions: 2.39.0, 2.38.0, 2.37.0, 2.36.0, 2.35.0, 2.34.0, 2.33.0
            Reporter: Luke Cwik
            Assignee: Luke Cwik
             Fix For: 2.40.0


JulHandlerPrintStream was not flushing in a loop for large byte arrays which meant that the carry over could be much larger then the assumed 6 bytes.

Saw these logs for a job:
