      The issue is described in some details under customer case 01952249. Reproducer added as testcase as part of the PR.

      In case of before completion fails to be processed it happens to be called a handler of preventCompletion. There is potential issue of receiving NullPointerException as rollback is called and there was not created lists (heuristic one in particular) as prepare was not processed.

      This situation could happen in case of trouble of WS-AT XTS of volatile participant.

      Let's look at the stack trace talk.

      First this is a failure of the beforeCompletion

      as that failure happens we can see the later NullPointer
