-----------------------------------------------------------------
First at all, I think that FacetedProjectFrameworkImpl initialization is very unsafe. I would create an issue at Eclipse Bugzilla without big hope of fixing that issue ;)
FacetedProjectFrameworkImpl is singleton and initialized in private constructor via a static synchronized method. The problem is that this constructor does too many things and it's very unsafe to do it in a synchronized method. There is a big possibility of getting a recursive invocation of this synchronized method.
Another issue is using Faceted Project Framework in plugin start methods. Start methods should be short and quick and they should not depend on complicated stuff such as Faceted Project Framework.
So I would avoid using Faceted Project Framework in JBossServerCorePlugin.start() and ESBProjectCorePlugin.start().
For JBossServerCorePlugin, adding a listener to FacetedProjectFramework may be a solution. See [^JBossServerCorePlugin.java.patch]
But for ESBProjectCorePlugin.start() I'm not sure. Do you really need to invoke VirtualReferenceUtilities.INSTANCE.addDefaultExtension() there?
