Prior to Java 9, there was once a console tool jhat . Try them.
I know that Oracle advises to use VisualVM , you can try it. But I don't know how he will behave. Did not work with him in conditions of limited memory.
Sorry if my answer didn't work for you. I would advise you to reduce the heap, and try dropping java again. If you are analyzing a memory leak, then it should happen on smaller heaps as well. At worst, you can profile memory allocation in a running java to find out who is allocating so many megabytes in the heap.
