[jbpm-users] [JBoss jBPM] - NPE with GPD after upgrading to 3.1.3.SP1

Hi, After upgrading JBoss jBPM JPDL designer from 3.1.0.GA to 3.1.3.SP1 (bundled with JBoss Tools), I can't open some process definition files with the graphical designer. I have the following stack trace : java.lang.NullPointerException | at org.jbpm.gd.jpdl.xml.EsbNodeMapper.accept(Unknown Source) | at
