"Re: Persisted timer task not firing on session restore" To view the discussion, visit: https://community.jboss.org/message/760609#760609 -------------------------------------------------------------- The first issue seems to be that, when restoring the session, it is detecting that a timer should have been fired and it is immediately firing this. Unfortunately, it's doing this before you have registered the necessary handlers, so it will fail finding those. The reason that it also tries to delete the process instance info is that due to this exception during the execution of the process instance, the process instance is aborted (as we cannot execute it correctly), leading to the deletion of the process instance info from the database. One way to avoid this is to use a configuration file to register the handlers. An example can be found here: https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/conf/META-INF https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/conf/META-INF If you put these two files in a META-INF folder in your classpath, you can specify your handlers in that configuration file (rather then registering them using the API). For the second issue (Unknown node instance type: org.jbpm.workflow.instance.node.ActionNodeInstance@c5c781), the engine is trying to persist the state of the process instance in the database while the process instance is still executing. This is usually caused by multiple threads running on the same process instance. Could you open a JIRA issue for this and attach the process and the java code you use to execute this, so we can try to reproduce?
