Review request for Ambari, Laszlo Puskas, Myroslav Papirkovskyy, Sebastian
Toader, and Sid Wagle.
Bugs: AMBARI-18956
https://issues.apache.org/jira/browse/AMBARI-18956
Repository: ambari
Description
-------
`EntityTransaction` may be marked
[rollback-only](http://docs.oracle.com/javaee/6/api/javax/persistence/EntityTransaction.html#setRollbackOnly())
due to exception. If `@Transactional` is not marked to `rollbackOn` such
exception, Ambari still attempts to commit the transaction. The end result for
the transaction is the same (rollback), but instead of the original exception a
`RollbackException` is reported, so information is lost.
