[esb-issues] [JBoss JIRA] Work stopped: (JBESB-3061) Classloader issue in jBPM integration

Classloader issue in jBPM integration ------------------------------------- Key: JBESB-3061 URL: https://jira.jboss.org/jira/browse/JBESB-3061 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Deployment, Process flow Affects Versions: 4.7 Reporter: Martin Vecera Assignee: Tom Fennelly Fix For: 4.7 CP1 Attachments: fail.tar.bz2 There is an issue that causes an exception during the task manipulation in jbpm-console. The steps to reproduce are little bit complicated. I was not able to find any easier way nor the steps work for 100%. You will need two quicstarts - bpm_orchestration4 and bpm_orchestration4_jca. The second one can be prepared as follows: 1) copy bpm_orchestration4 to bpm_orchestration4_jca 2) change jboss-esb.xml in bpm_orchestration4_jca to use a JMS JCA provider: <jms-jca-provider name="JBossMQ" connection-factory="ConnectionFactory" transacted="true"> ... </jms-jca-provider> Now start the server and follow these steps (please note that whenever you call startProcess, you must fulfill two tasks in the jbpm-console): 1) switch to bpm_orchestration4 2) ant deploy 3) ant deployProcess 4) ant startProcess 5) ant undeploy 6) ant deploy 7) ant startProcess 8) ant undeploy 9) switch to bpm_orchestration4_jca 10) ant deploy 11) delete the process definition in the jbpm-console 12) ant deployProcess 13) ant startProcess 14) ant undeploy 15) ant deploy 16) delete the process definition in the jbpm-console 17) ant deployProcess 18) ant startProcess 19) ant startProcess 20) ant undeploy 21) switch to bpm_orchestration4 22) ant deploy 23) ant startProcess 24) ant undeploy 25) ant deploy 26) ant startProcess 27) delete the process definition in the jbpm-console 28) ant deployProcess 29) ant startProcess 30) see the error during fulfilling the tasks in jbpm-console: Error completing task: An exception of type "org.jbpm.graph.def.DelegationException" was thrown. The message is: BaseClassLoader@3d3154fa{vfsfile:/home/mvecera/work/soa/50B1/jboss-as/server/default/deploy/Quickstart_bpm_orchestration4.esb/} classLoader is not connected to a domain (probably undeployed?) for class sun.reflect.MethodAccessorImpl Now, in thirty easy steps, you can also get an exception in the log: 15:56:06,990 ERROR [GraphElement] action threw exception:
