Ubuntu – Java 11 Required After Netbeans Update

Ubuntu 18.04.6 LTS

Netbeans updated (to version 19) over the weekend, and it is now completely broken. Whenever I try to start Netbeans, a pop-up shows up:

Pop-up Title: Java 11 or newer required
Pop-up Desc: Cannot run on older versions of Java than Java 11. Please install Java 11 or newer or use –jdkhome switch to point to its installation directory.

The pop-up can be dismissed but Netbeans will not open.

I do not want to use Java 11 (currently using Java 8) because some of my dependencies do not support it. What is the best way to fix this? Can I roll back this unwanted update? How do I prevent Netbeans from being updated in the future?

    Only the NetBeans binaries need the JDK 11, it doesn’t effect your projects!

    The Runtime JDK NetBeans uses does not influence the JDK range projects can use. – Release Notes

    Although NetBeans itself needs JDK 11, I think you can still build and run JDK 8 for your projects.

    See Overview of JDK 8 Support in NetBeans IDE.

    I also found this other StackOverflow question about pointing NetBeans at a particular JDK, in case you run into any trouble: How can I set the JDK NetBeans runs on?
