Unfortunately I do not know of any way of asking the JVM to state what objects it is removing as part of a GC. Actually, during a GC the JVM considers only live objects - it never even looks at dead objects that it collects. But you can take a heap dump - see http://java.sun.com/javase/6/docs/technotes/tools/share/jhat.html. If you can take a dump before a GC, that should give some idea of what is in the heap.
