Scott Marlow commented on AS7-3402:
-----------------------------------

As far as the client side, the javax.persistence.OptimisticLockException class is the error that the client side could of handled.  The issue is that has the underlying causing exception (org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [ejbserver.jpa.entity.users.User#660425]) which isn't on the client classpath.

Looking at the xnio stream closed error (http://pastie.org/3256858), I see the issue now.

When the AS7 EJB server side, calls org.jboss.as.ejb3.remote.protocol.versionone.AbstractMessageHandler.writeException() with an error exception class that is not on the clients classpath, the client side is going to stop reading the exception stream because it doesn't know about the org.hibernate.StaleObjectStateException class.

You already found the proper workaround (adding the Hibernate jars to the client classpath).  

The proper fix (IMO) would be to not return an error exception to the client that includes classes that the client doesn't know about.
