Question
Why does VisualVM terminate my program when attempting to view object allocation stack trace, and how do I fix it?
I'm cleaning up an application which has a few memory problems, the biggest being creating a bunch of short-lived int[]
which causes GC to fire like crazy:
When I right click int[]
and choose Take Snapshot and Show Allocation Stack Traces, my application closes and a warning box pops up saying Failed to obtain results snapshot. The application terminated:
The closest thing I found on the subject was a bug report which recommended running my profiled application with -Xnoclassgc. It didn't work, the results were the same.

The size of the crash log exceeded the character limit, so I had to place it elsewhere. Sorry.

Ok. So based on the crashlog obtained, it looks like you ran into a VisualVM bug already reported here:
JVM being profiled crashes
The submitter of the original bug narrowed this behavior down to Java8, so the best chance you have is running a VisualVM on an older (Java7) runtime. If this is an option for you, then you only need to download a Java7 JDK and run the VisualVM directly from there.
