to Jenkins Users

This is a weird one that I can't figure out yet.

I recently upgraded from Java 8 to Java 11.

This is on a Red Hat box that is running a single Jenkins instance behind apache

I am getting this error

Jenkins detected that you appear to be running more than one instance of Jenkins that share the same home directory 'XXXXX/jenkins’. This greatly confuses Jenkins and you will likely experience strange behaviors, so please correct the situation.

This Jenkins:
1462917624 contextPath="" at 123035@XXXXXX
Other Jenkins:
1462917624 contextPath="" at 123035@XXXXXX

Its telling me the same process.

If I check my running processes, there is only one Jenkins instance running, and yes it does have that PID listed above.
