Java is a multi-threaded process.
Are all threads stopped when that function gets called?

I don't have the script right now (I need to ask permission for disclosure).
But the script hooks Java methods using java().class().method() and file opens.
Guru mode is not used.

> Is this panic intermittent or does it happen every time?

So far only once, while running stability test for 8 hours.
