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
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:
