@plummercj Thanks a lot for your review!

I'm trying to fix mixed mode on Windows. I think we can unwind native stacks with [this change](https://github.com/YaSuenag/jdk/commit/71fc6df3d9e46e03d956f08c03fdefc6e12586fd), but it is not enough for Java frames - I think we can see all of them if we modify after this PR.
