During development, on application redeploy, I was seeing an error like this:
Java5:
15:27:34,647 WARN [ServiceController] Problem starting service jboss.j2ee:service=EJB3,module=heart-biz.jar
java.lang.LinkageError: loader constraints violated when linking com/kink/heart/biz/admin/i/LiveShowData class
Java6 (it seems they tried to improve the error a bit):
15:15:46,205 WARN [ServiceController] Problem starting service jboss.j2ee:service=EJB3,module=heart-biz.jar
java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "com.kink.heart.biz.content.ContentMgrBean.getLiveShow(Ljava/lang/Long;)Lcom/kink/heart/biz/admin/i/LiveShowData;" the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) of the current class, com/kink/heart/biz/content/ContentMgrBean, and the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) for interface com/kink/heart/biz/content/i/ContentMgr have different Class objects for the type com/kink/heart/biz/admin/i/LiveShowData used in the signature
Well, after finding this JBoss FAQ page, I followed the directions on it. They were really helpful!
Once I looked up the offending class (LiveShowData), it became instantly clear what the problem was:
### Instance0 found in UCL: [email protected]{ url=file:/Users/jonstevens/checkout/jboss-heart/server/default/tmp/deploy/tmp54117z-ads.ear ,addedOrder=40}
### Instance1 found in UCL: [email protected]{ url=file:/Users/jonstevens/checkout/jboss-heart/server/default/tmp/deploy/tmp54118heart.ear ,addedOrder=41}
Sync up the two jar's which contain my EJB3 interfaces and suddenly everything is working again.

You love content on a wiki started originally by me. This means I win the wiki argument we had years ago :-)
You win! Thanks Andrew!
If only ServiceController just included a link to that page in the exception message. =)
except they replaced my wonderful wiki with sensible names with one that names things DOC-12342134 :-(
Yeah really. JBoss error messages suck. How are things? dumb question, you get to work in porn :-)
