About HornetQ issue, it can be a problem when creating hornetq session. In this class: https://github.com/droolsjbpm/jbpm/blob/5.1.x/jbpm-human-task/src/main/ja... https://github.com/droolsjbpm/jbpm/blob/5.1.x/jbpm-human-task/src/main/ja... The NPE may indicate the session is null. Maybe the nor But it should be created in connect method. -Could you check please if there is an error before? (line 122 of the class, } catch (Exception e) { logger.error(e.getMessage()); return false; } ) - If you don't see nothing wrong in logs, could you debug connect method to see if hornetq session is being created ok?
