Hello JBoss As 7.1 Guru !

I have an application EJB3 / JPA based and when I deploy the application the first time , everything is ok and everything start fine.

The second time or some times after, the server is giving me this error Can't find a deployment unit named TEST in subdeployment "TEST.jar".

I know it's not my code (well .. I think I know) because it start fine the first time and after a couple of time that I delete the .undeployed file, everything is back to normal and the application is deploying without any issue.

Perhaps it's because my DataSource is not closed properly or something like that ?

Did someone already had something like that, it's pretty hard to debug.?

Here is the stacktrace
