Problem with SerializableProxy when de-serializing in a remote client
---------------------------------------------------------------------

                 Key: JBAS-3952
                 URL: http://jira.jboss.com/jira/browse/JBAS-3952
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: EJB3, Hibernate service
    Affects Versions: JBossAS-4.0.5.GA
         Environment: Windows Vista and Windows XP, Java 1.5.0 Update 10 and Java 1.6.0
            Reporter: Frank Ulbricht
         Assigned To: Bill Burke


After calling a SessionBean method that returns an entity with a lazy relation there is an problem with de-serialization on the client side. The lazy field cannot not be assigned because of a ClassCastException. In other projects the same happens after a method returns the result of a query where lazy fields are involved. The problem occurs only with lazy fields. The is a simple test case attached with the problem code line marked.

Here is the complete stacktrace:
