Tom Jenkinson updated JBTM-2767:
--------------------------------
Description:
If an XAResource throws a heuristic we can't forget it but we do clean up some transactional state meaning it will need reloading from disk (after the heuristic is cleared) before it can be meaningfully used again. In the state where it can't be meaningfully used we need to provide something to the caller.

was:
I hit a trouble similar to JBEAP-5638 but in this case for {{JTS}}. I'm not able to recover heuristic transaction for scenario
{quote}
* test client sends prepare command
* test client sends commit command
* first XAResource commits, secondXAResource throws {{XAException#XAER_RMERR}} on commit start
* test client gets error code {{XAException#XA_HEURMIX}}
* now the transaction participant is in heuristic state
* tried to commit the created txn -> fails as in heuristic and can't be operated
* using {{:recover}} command for the transaction participant
* tried to commit the txn -> expecting the commit succeed and txn is committed
{quote}
There are two troubles. First is {{NullPointerException}} is thrown during a try to commit transaction in heuristic state [1].
Second is not possible to read transaction participant from object store via {{jboss-cli}} commands (even when {{expose-all-logs}} is used) and that way it's not possible to call {{recover}} the participant in heuristic state.
