I find myself supporting an application which I didn't write and which makes heavy use of JBPM 3.3. Occasionally it starts spewing exceptions non-stop

java.lang.NullPointerException

I have no source code for the GraphElement, don't know where to find it and there is not a single class in there from my application. I don't know where to start trying to get to the bottom of this. Any help greatly appreciated - is this a bug in JBPM? Was it fixed in a different version? Can anyone point me to a workaround?
