Scoped plan with EclipseLink runs into problems [message #875857]

Eclipse Virgo 3.5.0M4 Jetty edition

So I have a plan that when unscoped (scoped="false") everything works fine. When scoped though I run into the exception below. The error is:

Internal Exception: org.eclipse.virgo.kernel.osgi.framework.ExtendedClassNotFoundException: org.eclipse.persistence.indirection.IndirectList in KernelBundleClassLoader: [bundle=server-1-synthetic.context_1.0.0]

In my case Spring is wiring together my JPA context. I assume that it must be doing some magic with the thread context classloader. I read

http://underlap.blogspot.com/2011/02/thread-context-class-loading-in-virgo.html

which was great and got me past the initial class-not-found issues as my bundle needed to export a package to be included in the synthetic context. This one has me stumped though. As far as I can tell:

* I've exported everything from my bundles needed by the code using the thread context.
* org.eclipse.persistence bundle's export the package org.eclipse.persistence.indirection (and more)

Is there any way to flush out what the problem might be here?

So I'm wondering, given a scenario like the one depicted in

http://underlap.blogspot.com/2011/02/thread-context-class-loading-in-virgo.html

Where bundles 'A' and 'B' are in a scoped application that calls a library bundle 'L' outside of the application, 'L' can "see" packages exported by 'A' and 'B'.

What if 'A' or 'B' imported something from bundle 'E' that also lived outside of the scoped application. Should/would 'L' be able to "see" packages in 'E'?

The scenario I raise above seems to indicate that packages in 'E' are not visible, however I think that this is why the scoped application is failing. Do my 'A' and 'B' bundles need to re-export the 'E' packages in order for 'L' to see them?
