Description Tomas Hurka 2016-11-02 14:53:03 UTC 
Reported against VisualVM <https://github.com/visualvm/visualvm.src/issues/4>:

I'm trying to analyze a large heap dump (file is around 60GB) using VisualVM 1.3.9. There are a large number of int[] instances consuming the vast majority of the heap space, and I am trying to get to the bottom of why. However, when I click on one of the instances in the instance view, which starts to determine the referrers, it makes it about 2% through and then throws a NullPointerException (as seen in the error button hover).

If I navigate to the OQL window and try it that way via referrers(heap.findObject("0x7fa8fb109ae0")), it runs for a while before printing:

javax.script.ScriptException: ReferenceError: "println" is not defined in at line number 1030

Any ideas on what the problem could be or how I could diagnose further? I am using Sun JDK 1.8.0_60 on Mac OS X, VisualVM 1.3.9.
Comment 1 Tomas Hurka 2016-11-02 14:55:12 UTC 
This JDK 8+ bug. Nashorn does not have 'println' in global scope. See https://bugs.openjdk.java.net/browse/JDK-8035181
Comment 2 Tomas Hurka 2016-11-02 15:06:42 UTC
