Hello Together, i found out the cause of this. It was not a good idea to use the currentJpbmContext to make a data base lookup. Instead of: JbpmContext jbpmContext = JbpmContext.getCurrentJbpmContext(); is better JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance(); | JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext(); // This will change the jpbmContext object and have some issue when resuming the process execution later. So before loocking up the data base first get a new jbpmContext object, performe any operation on the DB and close it by leaving the methode. Hope it could help others encoutering the same problem.
