maybe a java bug

[umjammer]

old code (after the patch below)

causes crash around java.nio.DirectIntBufferU#get(int).

after the patch above, this program will have a bug that closing dict before using that.

but on catalina the program after the patch works, it contains a bug though.

on the other hand, on monterey the program after patch cause crash. java should throw an exception.

i couldn't create a small sample bug reproducer. because there is no way to create a java.nio.DirectIntBufferU instance.
