InVM transport problem

[haagenhasle]

Hi!

I've just upgraded my server to 4.3.GA, and I'm busy testing it out now. I tried to use the new InVM transport instead of JMS. At first glance it looks awesome, but then an exception occurs in my action something strange happens. When I use JMS, my code cathes a FaultMessageException from the call to the ServiceInvoker. When I use InVM transport, the exception seems to disappear.

Any comments on this? I would have thought that the exception-handling should be the same regardless of which transport I use, so this looks like a bug to me.

Let me add that I see that the exception is not swallowd entirely, I see it in message.getFault(). But a FaultMessageException is never thrown.

Haagen, would you mind creating a JIRA and attaching a sample example that reproduces this?

Sure, I'll create the Jira. It's easy enough to reproduce, I can just modify the native_client quickstart to use InVM transport, and make sure it throws an exception in MyAction

public Message playWithMessage(Message message) throws Exception {
 Body msgBody = message.getBody();
 String contents = (String) msgBody.get();

 if( contents.equalsIgnoreCase("throwexception") ) {
 throw new ActionProcessingException(new RuntimeException("Throw exception"));
 }
 // Reset the message body contents with the response...
 msgBody.add(("Hello From ESB MyAction: " + contents));

 return message;
 }

(I had to add ActionProcessingException as an import as well.)
and

<?xml version = "1.0" encoding = "UTF-8"?>
<jbossesb
 xmlns="http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/etc/schemas/xml/jbossesb-1.0.1.xsd" parameterReloadSecs="5">

 <action name="displayAction"

 </action>
 <action name="playAction"

 </action>
 <action name="finalDisplayAction"

 process="displayMessage">
 <property name="exceptionMethod" value="exceptionHandler"/>
 </action>
 </actions>
 </service>
 </services>

</jbossesb>

Note that it makes no difference if I throw an ActionProcessingException, ActionProcessingFaultException or RuntimeException from the action.
