Would be good to go ahead with this.
It seems on Windows that JavaThread with undefined stack base/size can be seen via JavaThreadIteratorWithHandle.
There may be more to investigate as to why this is happening, but guarding against it as a quick fix seems good as the failure is quite noisy.
I'm testing it too, will let you know if anything interesting happens.

Nothing interesting happened. Meaning, no crashes!
