[ https://issues.jboss.org/browse/JBTM-2767?page=com.atlassian.jira.plugin.... ] 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.

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.
