You should understand that System.gc(); does not call garbage collector. It just politely asks GC to remove some garbage. GC decides what to do and when to start itself. So, do not expect that you will see any immediate effect when calling System.gc();, assigning null to variable etc.

GC removes all objects that cannot be accessed by any way. So if code exited block where variable was defined the object can be removed. Assiging null removes the reference. Weak reference does not prevent GC from removing the object.

I hope this explanation helps.
