Is graphical view with drill down of Class count references to other class instances  exists in JMC as it was in JRocket Mission Control?

I refer to the view of rectangular with arrows and count on them to other rectangular, each rectangular represent an instance of object and you can zoom in or scroll or click on the rectangular to expand it.


This feature is the best method to detect the cause of memory leak  - who hold your most large/increased instances.

    That wonderful tool was called Memleak. We currently do not have the features required for something similar in HotSpot, but we are looking at implementing a next generation tool for on-line heap analysis aimed at solving memory leaks in production systems. Stay tuned!

    Well, This is the feature why I look at JMC again. I had success to work with Jrocket Mission control and  memleak to locate memleak in application running on TOMCAT6/JRE6.

    Do you know that JRocket can raised TOMCAT7 originally run on JRE7 and how, and which libs should be added to JRocket path.

    Regarding TOMCAT8 I believe it is a lost case, due to lambda expression been used and is part of new java byte code processing now. (At least Java Decompiler programs/plug-ins need to handle it specifically)

    No, there is not JDK 7 version of JRockit, and there is no plan to release such a version either.
