Trustin Lee resolved DIRMINA-492.
---------------------------------

    Resolution: Fixed
      Assignee: Trustin Lee

Thank you so much for the reproduceable code.  I successfully reproduced the problem and it was turned out to be the problem of DecodingStateProtocolDecoder.  It has been fixed now; I made sure your test run without an exception.
