ExceptionHandler / changes since 3.2GA

[mpet]

Hello,

I used a global exception handler in my process definition, like the following:

<?xml version="1.0" encoding="UTF-8"?>
<process-definition
 xmlns="urn:jbpm.org:jpdl-3.2"
 name="simple">
 <start-state name="start">
 <transition name="to_state" to="first">
 <action name="action" class="com.sample.action.NoHandlerAvailable">
 <message>Going to the first state!</message>
 </action>
 </transition>
 </start-state>
 <state name="first">
 <transition to="end"></transition>
 </state>
 <end-state name="end"></end-state>
 <exception-handler>
 <action class="com.sample.action.TestExceptionHandler">
 </action>
 </exception-handler>
</process-definition>

In the above example, the action handler com.sample.action.NoHandlerAvailable is not available (or maybe causes an exception). In case the exception handler class is not available (or causes an exception itself), 3.1.2 and 3.2GA stopped executing the process flow. After upgrading to 3.2.2 or above (have not tried 3.2.1), if the exception handler class is not available or causes an exception, that exception seems to be handled by the same exception handler - causing an (infinite ?) loop.

Might this be a bug or is the new behaviour intended? Or am I missing something?

Thanks for any help.

Hmm.. I'm completely a noob in using exceptionhandlers in jBPM. But at least the unavailability of an exceptionhandler should not occur and it should not throw an exception iteself. Otoh, an infinit loop should not occur either. Please file a jira issue and see what comes out of it.

Thanks, I filled in a jira issue as suggested: https://jira.jboss.org/jira/browse/JBPM-1887

Okay I added a comment (and solution proposal) in JIRA and would volunteer to commit it... But I want to wait for possible feedback from Tom first...

Cheers

You are right. It is really funny. I tried exception handler which throws exception and this exception was caught by this handler again causing infinite loop. I use jBPM 3.2.2.
