With the concurrent low pause collector how can I tell how much floating garbage is left?
Because the application threads and the GC thread run concurrently, an object that is live at the beginning of a collection and which the GC thread has marked as live may die by the end of the collection. Such objects are referred to as floating garbage. The amount of floating garbage can be inferred if a full compacting collection occurs immediate following a concurrent collection. Any reduction in the heap size is due to floating garbage.
