Hi,
In a processdef, one fork leads to several states, each state has a timer attached. The
idea is to do concurrent async executions through the TimerServiceBean. However, get
exceptions, when those states changing to join node.

This is acceptable if things can rollback. However when this happens, timers still been
cancelled, so the actions will never been retried and the process sitting dead:

Should Timer.cancel() rollback facing a RuntimeException in JTA transactions? I tried both
JTA and CMP for hibernate, no luck. Did I miss something?
