I suppose you pack the same framework classes into some of your deployable archives.
Could you elaborate what does that packing framework classes mean?
That's not a stacktrace. It's just a INFO level message (which really should have been a DEBUG or TRACE level message). Just ignore it. All it's saying is that one of the deployers within JBoss AS has found a EJB jar and is going to process it. Not something the user should care about.
