Looks like you are using the latest Java 80 on your system. I would
suggest you open a PMR to my team for further investigation. thanks.From
the stack , looks like it's an issue from JIT component. For this kind of
crash , we usually need "javacore", "core" dumps together with the 4700
0012 vlogs collected. thx.

Best regards.
