I apologize if this is not the right place to ask my question.
I read basil article on this move to Java 11 or higher. One thing that I could find no mention of was use of older JDKs via Global Tools. I would hope that still works, as I have old software to support that has not reached end of life. However, no effort will be made to update those old projects from Java 8.
I expect it will, but I have to ask - will using JDK 8 in Global Tools will still work?

littleccguy Yes that should work just fine. In general you can use any JDK for your actual builds (as opposed to running Jenkins). Feel free to download the latest weekly release and play around with your use case locally if that would make you more comfortable.
