JBoss EJB MessageContext Exception

[pek]

I start JBoss and run my application. Everything is running correctly.
I close and exit my application and leave JBoss running (I am using
JBossIDE). After a while JBoss throws this exception:

"22:29:38,406 INFO [STDOUT] Exception in thread "Timer-4"

Whenever this exception is thrown I cannot redeploy correctly my
application. When I try deploying my J2EE (it include EJB3.0,
Persistence, and Web modules) I get an exception (among the long log
while deploying). The exception is at the end of this post (part of
it). The only way to start my app again is to restart JBoss and
deploy. Any ideas..?

Thank you in advance
