Running archive build on project node of "Package archives" view throws CCE.

[code]
java.lang.ClassCastException: org.jboss.ide.eclipse.archives.ui.providers.ArchivesContentProviderDelegate$WrappedProject cannot be cast to org.jboss.ide.eclipse.archives.core.model.IArchiveNode
at org.jboss.ide.eclipse.archives.ui.actions.BuildAction$1.run(BuildAction.java:77)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
[/code]

Process:

1. create a Java Project
2. create deploy, EarContent and WarContent folders
3. create an EAR package (Project archives view)
3.1. destination to deploy folder
3.2. exploded
4. delete default fileset

This already throws CCE trying build.
