Thanks for the detailed report. I am however not able to find suitable java application, where this can be reproduced. Is there a particular application I can use to reproduce...

Please provide Profiler->CPU settings.

It would be great, if you can provide the screenshot to illustrate the issue. Thanks.

Screenshot will be useful. I still don't know if you are talking about profiler, sampler, heapviewer or plain thread dump.

BTW: You should be able to use '[Go to Source](https://visualvm.github.io/sourcessupport.html)' and it will find the correct anonymous class and opens it in your favourite editor/IDE.

This can happen if there is another java application, which were started when your computer had different IP address (for example you were connected via WiFi started Java app and...

Can anyone provide clear steps to reproduce it?

You are right that is can be useful. Sampling uses JMX to get the stack traces. Unfortunately the signature is not part of stack trace obtained this way.

Thanks for the report. The detection of the broken heap dump was added by [NetBeans bugfix #254900](https://bz.apache.org/netbeans/show_bug.cgi?id=254900). Older version of VisualVM does have this fix, so it will try to...

One more question: do you how the heap dump was obtained? What command was used?
