This is what I've pushed in (also added MetaDataRetrieval.isEmpty()). I think it should do the trick.

But if I want to remove the hack with joinpoint being ControllerContext aware, I need to get the context's name from somewhere.

  |       MetaData instanceMetaData = metaData.getScopeMetaData(instanceKey);
  |       if (instanceMetaData != null && instanceMetaData.isEmpty() == false)
  |       {
  |          return true;  
  |       }

Perhaps put in in the MetaData under 'ControllerContext.name' name?
And push in/out this info in KernelControllerContextAction.dispatchJoinPoint invocation?
Or just simply put in in for good when we first create MetaData for context - in PreInstallAction?
