[jboss-jira] [JBoss JIRA] (AS7-3229) OptionalDataException failure during deserialization of nested bean

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/AS7-3229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12659412#comment-12659412 ] 

Scott Marlow commented on AS7-3229:
-----------------------------------

Made progress on reducing the test down to a smaller test that still fails (playing on https://github.com/scottmarlow/jboss-as/tree/cluster9_hacktest).  Will divide conquer some more to reduce further.  After removing the XPC from the test, I still could reproduce the "java.lang.IllegalArgumentException: object is not an instance of declaring class" (that seemed to occur more often).  By success, I mean that three consecutive test runs, passed.

The following passes (the second clustered bean is not injected anymore which made the difference).  I will add the XPC back in and if that works, will inject the second bean but try not tagging the second bean as clustered.

> The bug didn't recreate with the simple test https://github.com/scottmarlow/jboss-as/commits/AS7-3229.  Might need to push the XPC serialization changes before it can be recreated.
