That is not a bug but an indicator that something in your setup is not correct.
Search for the error message failed to map segment from shared object and you will get pointers what could be wrong.
Yes, this must be a bug as I am unable to start a newly installed jenkins on any RHEL 8 machine – I have tried 3 different machines with new RHEL 8 installs. Jenkins was installed using the redhat instructions here: Linux (jenkins.io)
Nothing has been setup yet - only RHEL 8 and jenkins. Additionally the /var/lib/jenkins/.cache/JNA/temp/jna17258145716752850398.tmp file complained about only exists when jenkins attempts to start, it does not exist beforehand and it does not exist afterwards, jenkins must create it somehow.
The entire log when attempting to start jenkins on any RHEL 8 machine is:

I assume you get an image from your IT department so it is no surprise that all 3 attempts fail as the image is the same.
When I look for this error I found many pointers that the problem is with writing to /tmp. So you should check whether the user under which jenkins runs (this is probably the user with id jenkins) is able to write there.
If there would be a bug in Jenkins, then thousands of users would have a problem which is not the case.
I found the same “pointers” to /tmp. However, the error does not indicate a file in /tmp, it indicates a file in /var/lib/jenkins/.cache/, which is where the rest of jenkins is, everything is owned by jenkins:jenkins. and, indeed, the file was created by jenkins.
Another possibility is that /tmp is mounted with noexec. You can check this but copying an executable there and try to run it.
You would then need to try to mount /tmp so that you can execute from there or change the tempdir for the java process to a path that allows executing things.
