Extract thread dump from a heap dump

I have a huge heap dump (around 12GB) and it will take forever to open it with MAT or jvisualvm. I only want to get the thread dump out of it without indexing the objects. Is it possible with the above or any other tools?

The latest snapshot versions of Memory Analyzer (preview of 1.11) have the ability to discard objects on parse. Having a discard ratio of 100% with a pattern of (?!.Thread). would discard all objects except those of a type with 'Thread' in the classname. That might speed up parsing, though the parsed dump would be nearly useless, but it would have a thread dump (but without thread names or local variables) which might be enough for your purposes.

Had the same problem recently.

I just pushed the project doing it on GitHub. I know, it is way too late, but probably will save some time to someone in future.
