IsLocalProxyFactoryInterceptor routes to local proxy factory instead of a remote proxy factory
----------------------------------------------------------------------------------------------

                 Key: EJBTHREE-1884
                 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1884
             Project: EJB 3.0
          Issue Type: Bug
          Components: proxy-impl
    Affects Versions: 1.1.11
            Reporter: jaikiran pai
            Assignee: jaikiran pai


The fix EJBTHREE-1868 exposed a bug in the way the IsLocalProxyFactoryInterceptor is used. Mail conversation below:


Turns out, the fix for EJBTHREE-1868 just exposed this other existing bug. This forum thread in EJB3 design forum explains the purpose of IsLocalProxyFactoryInterceptor http://www.jboss.org/index.html?module=bb&op=viewtopic&t=104924. The ProxyObjectFactory#getObjectInstance invokes createProxyFactoryProxy which internally ends up using the local IsLocalProxyFactoryInterceptor instance. All this happens on the client and the  IsLocalProxyFactoryInterceptor is never serialized. Effectively  this ends up being  routed to the local proxy factory when the same bean is available on more than one running instance of the server.

After this "fix", Our hudson run has been reporting failures with Clustered ForeignPartitionLocalInterceptorUnitTestCase

Bean on node1 looks up same bean on node2 (by passing the PROVIDER_URL) to initial context. But the IsLocalProxyFactoryInterceptor after this fix identifies this as a local call (because it finds the same bean registered with the Dispatcher locally). As a result, a local proxy is returned and the test fails.
