Summary: BinaryTreeDictionary is typedef'ed as AFLBinaryTreeDictionary in vmStructs and in SA we still use old name for that. FreeList now is a template based class which is not reflect in SA type library. When SA does calculation of heap for CMS, the former will cause failure to retrieve BinaryTreeDictionary  sine the rename. The later will fail wherever it is used in SA.

Summary: G1 now uses two reference processors - one is used by concurrent marking and the other is used by STW GCs (both full and incremental evacuation pauses). In an evacuation pause, the reference processor is embedded into the closures used to scan objects. Doing so causes causes reference objects to be 'discovered' by the reference processor. At the end of the evacuation pause, these discovered reference objects are processed - preserving (and copying) referent objects (and their reachable graphs) as appropriate.
