--------------------------------------------------------------
When I export the BPMN exported from Intalio, also known as Eclipse STP BPMN model (modeler.bpmn) to jPDL by using JBoss tool,
This error is shown every time I choose my process pool and click on the next button (in the export window BPMN to jPDL)

Enviroment: 
*
*
*Eclipse 3.6.1 (Helios SR1) with JBoss tools 3.2.0 installed*

*Error logs: "Unhandled event loop exception"*
