Description
Liveness Analysis feature in SA computes liveness of all the objects of one type together. if we have a heap of large size containing many objects, it always runs Out Of Memory. (e.g. one customer had a heap size of 1.5gb and it contained 122,169,720 String objects which were filling up heap; SA could not do the liveness analysis for these String objects even with -Xmx2048m).

A facility can be added where one can compute the liveness of one single object which would need much less memory.
