JESS: Called method threw an exception

[Richard Kasperowski]

Someone else on the development team changed a bean that I use for definstance facts. Now, sometimes when I definstance the object, I see an error message like this:

Jess reported an error in routine DefinstanceList.createFact
while executing (definstance AlarmFaultData (fetch alarm)).
Message: Called method threw an exception.
Program text: ( definstance AlarmFaultData ( fetch alarm ) ) at line 1.
at jess.DefinstanceList.createFact(DefinstanceList.java:121)
at jess.DefinstanceList.definstance(DefinstanceList.java:176)
at jess.Rete.definstance(Rete.java:1134)
at jess.Definstance.call(ReflectFunctions.java:776)

at jess.Rete.executeCommand(Rete.java:1205)
at com.giantloop.adapter.ext.expertSys.JessExpertSystem.assertFact(JessExpertSystem.java:295)

That's cool: the bean is now broken because one of its methods is throwing an exception.

My problem is that the error message isn't verbose enough. *Which* method of which class threw what exception? Can you consider this enhancement request? (I'm using Jess 6.0.) (And I'm messing with the Jess source code myself so I can identify and fix the culprit.)

Thanks,
