    RunRecoveryException: BufferOverflowException on startup

      Hi all.

      I get the above when constructing the XAEnvironment if the application was kill -9'd between a prepare() and a sync().

      prepare(), sync() and prepare(), commit(), sync() work.
      prepare() and prepare(), commit() do not.

      The problem occurs with both 3.1.0 and 3.2.13.
      I tried to setSync(true) the TransactionConfig, with no effect.

      My environment config is:

      envConfig.setAllowCreate( true );
      envConfig.setTransactional( true );

      Full stack trace:

          Hello user549022,

          Thanks for sending this along. I've opened an internal SR for this [15293] so I'd like to take this offline. If you are able to send me your RestartTest so that I can run this myself, that would be great. Please email me at charles.lamb @ where you would expect.com.

          Thanks very much.

            Whoops.. sorry.. forgot the end.

            I was wondering what I was doing wrong and - if not - what I could do about it?

            I have a small test program available to anyone interested.

              Hi Matthieu,

              This is SR 15293 in our internal system. Thank you for locating the problem. For anyone interested, it turns out that Matthieu uses foreign encoding in his XidImpl class. During recovery, we log an informational message if we find an orphaned prepare record from a 2PC. The log message does an Xid.toString() but does not account correctly for the difference between String.length() and String.getBytes().length when non 8-bit encodings are used (our bug, not his).

              JE release 3.2.15 or later fixes this. If anyone needs a fix for this bug, please let me know and I can email it to you. I'll post the diffs here on this forum -- they're very simple.
