> If you run a process definition below with ExceptionActionHandler which t=
hrows IllegalArgumentException, the first exception will be handled by the =
first exception handler and the second exception won't be handled --- will =
be thrown as a DelegationException to the client.
> This behavior was introduced by JBPM-1887 to avoid infinite loop. But Exe=
cutionContext.exception can be cleared after handling the exception. Then a=
voiding loop and using multiple exception handlers will be achieved at a ti=
me. =
