Kevin Conner commented on JBESB-1374:
-------------------------------------

Any RuntimeException caught by the ActionProcessingPipeline, whatever the source, will cause a rollback (as will Error subclasses).

The responsibility for deciding whether a RuntimeException should be wrapped/unwrapped lies within the jBPM  and integration code.  It is as valid for this code to choose to respond to the originating service with a fault message as it would be to cause a JTA rollback.

If this RuntimeException was resulting in an inconsistent state within the jBPM then I would expect the jBPM code to call setRollbackOnly on the active transaction.  As this hasn't happened we can only assume that the jBPM state is consistent and that we should honour their intentions.

> When used distributed tranasctions the transaction is rolled back when runtime exception is thrown. Unfortunately the jBPM encapsulates RuntimeExceptions into JBPMExceptions that are checked. Thus the rollback is not executed.
> Also it needs to be checked there there is no other way in ESB that will cause RuntimException to be changed to checked Exception.
