IAE or OptionalDataException failure preventing clustering of nested bean (deserialization fails)

This recreates with the test at https://github.com/scottmarlow/jboss-as/tree/AS7-3229. The test just injects an additional EJB bean into the current org.jboss.as.test.clustering.unmanaged.ejb3.stateful.bean.StatefulBean.

http://pastie.org/3205455 is an example of the OptionalDataException that I just got (I had to make one more test change, should recreate now).

To recreate, grab my change from the above branch and cd into as7/testsuite/integration/clust and run "ant clean install" as you normally would.
