WindowsTableHeaderUI error on client 7.9.3

[mike.miller]

I’m having an issue that just popped up today. I’m not able to view any tables in my client. They just won’t load. When I look at Help → Diagnostics → Console, I see several errors starting with the following error.

Exception in thread “AWT-EventQueue-0” java.lang.NoClassDefFoundError: com/sun/java/swing/plaf/windows/WindowsTableHeaderUI

The machine I’m running this client on is running fedora 35 so I tried launching a virtual windows machine and everything works fine and another guy in the office is running mac OS and he isn’t having any trouble. I’ve been using this machine for a while and haven’t had any trouble until today. Any suggestions on where to go from here?

The only place in the table that uses java swing is my header configuration, but even when I disable the configureHeaderStyle I get the same error.
