Project Archives from JBDS 1.1 project don't work anymore

After installing JBDS 2.0 Beta 1, I pulled in my Eclipse workspace from JBDS 1.1. When you use the Project Archives view and click on a project, and then click to expand the tree, it seems like Eclipse goes into an endless loop. I have captured two screenshots from my desktop showing the progress view of expanding the archive that shows the two outputs that it constantly goes back and forth between (very fast by the way).

Also, if you right click and select build full archive, you get the following exception:

An internal error occurred during: "Build Archive Node".

org.jboss.ide.eclipse.archives.ui.providers.ArchivesContentProviderDelegate$WrappedProject cannot be cast to org.jboss.ide.eclipse.archives.core.model.IArchiveNode

I cannot find how I can get a full stack trace, so if you could point me in the right direction, I can capture that, but couldn't find how to get more information on the error.

The endless loop seems very strange as well.
