Running latest rawhide, targeted enforcing:

Running 'java -jar mindterm.jar' with mindterm-3.1.2 produced AVC.

Putting in permissive mode and running, I get these:

or

allow xdm_xserver_t java_t:shm { write unix_read getattr unix_write
associate read };


BTW, the app appears to run in enforcing mode, even with the AVC.
Here is the only enforcing AVC:
