Build Identifier: I20110613-1736

If I run a successful build and then run validate again the content.jar is deleted. I would not expect anything in the build/final directory to be touched by a validation pass. If I then try to regenerate content.jar by running build again I get the following error:

java.lang.ClassCastException: org.eclipse.equinox.internal.p2.artifact.repository.CompositeArtifactRepository cannot be cast to org.eclipse.equinox.p2.repository.artifact.IFileArtifactRepository
	at org.eclipse.b3.aggregator.engine.Builder.getAggregationArtifactRepository(Builder.java:730)
	at org.eclipse.b3.aggregator.engine.Builder.initializeArtifactMirroring(Builder.java:1004)
	at org.eclipse.b3.aggregator.engine.Builder.run(Builder.java:1650)
	at org.eclipse.b3.aggregator.presentation.AggregatorActionBarContributor$BuildAggregationAction$1.run(AggregatorActionBarContributor.java:292)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

If I run the build again it does not fail, but the metadata can sometimes be broken.

Reproducible: Always

Steps to Reproduce:
1. Run a repo build and wait for it to complete successfully
2. Validate the model
3. Check if content.jar is present (should not be)
4. Run a build again - get CCE.
