SELinux is preventing java from search access on the directory /sys/fs/cgroup.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that java should be allowed search access on the cgroup directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'java' --raw | audit2allow -M my-java
# semodule -X 300 -i my-java.pp
