Does JProfiler Have A Reachability Scope View Like YourKit?

I am analysing a heap dump created by jmap.

YourKit has a "Reachability scope" which shows objects distributed according to their reachability scope, i.e. on how/whether they are reachable from GC roots
http://www.yourkit.com/docs/95/help/reachability.jsp

I am interested in seeing the "Objects unreachable from GC roots but not yet collected".

Does JProfiler have such a view?

For that matter, is there anyway to get this using jhat, VisualVM or IBM MAT?

Solution

  • Currently not, but I've added this for 8.1, there will be an inspection "Unreachable objects" in the heap walker.
