Undeployment cleanup failed

[tomyeh]

Since upgrading from 3.0.8 to 3.2.1, the following exception occurs when undeploying my application from the server:

22:09:34,159 ERROR [MainDeployer] Undeployment cleanup failed: file:/F:/usr/jboss/server/potix/t

----
Any hint? If don't deploy my app, there is no problem to shutdown the server.

I cleaned up my deploy directory to hold only:
jboss-jca.sar* jbossweb-jetty.sar/ sqlexception-service.xml*
jboss-local-jdbc.rar* mail-service.xml* transaction-service.xml*
jboss-xa-jdbc.rar* postgres-ds.xml*

Thansk and Regards,
Tom

I also found, upon starting up, there are such kind of erros:

mbeans:
, org.jboss.deployment.DeploymentInfo@f7c1cdfa { url=file:/F:/usr/jboss/server/potix/tmp/deploy/server/potix/deploy1/i3e.ear/16.i3e.ear-contents/i3lb.jar }
deployer: null
status: Starting
state: START_SUBDEPLOYMENTS
watch: file:/F:/usr/jboss/server/potix/tmp/deploy/server/potix/deploy1/i3e.ear/16.i3e.ear-contents/i3lb.jar
lastDeployed: 1064239652504
lastModified: 1064239640783

After examing the source codes, the null pointer seems caused by a null deployer, but why the deployer is null.

In this case, i3lb.jar is simply a library -- doesn't contain EJB implements (though invoking some EJB).
