Subject [jira] Closed: (DIRMINA-91) BufferUnderflowException while calling ProtocolViolationException.getMessage()
Date Wed, 21 Sep 2005 16:37:27 GMT
     [ http://issues.apache.org/jira/browse/DIRMINA-91?page=all ]
     
Trustin Lee closed DIRMINA-91:
------------------------------

    Resolution: Fixed

I found that IoAdapter don't delay the release of the buffer which caused decoding failure.
 The buffer will be released immediately when IoAdapter.SessionHandlerAdapter.dataRead() method
returns regardless ProtocolViolationException uses it or not.

I fixed this issue by acquiring the buffer once more when I create ProtocolViolationException.
