Answer 1

This problem can reproduce in simplified chinese Windows with gb18030 support package installed. I trace it with process monitor, saw the process end with some buffer overflow error, while loading font file named simsun gb18030(something like this, I don't remember clearly.) this problem exist at any version of hotspot jvm after JDK 11. but for j9 vm, there's no problem.
