Thanks, I have confirmed that adding the new JDK via the Project Properties -> Manage Java Platforms for the platform app and selecting it results in the same exceptions as changing the JDK home in netbeans.conf (which I changed back to JDK 14). Using JDK 14 doesn't throw any exceptions, but JDK 17 does. This is pretty low on my list of priorities, since I can either just use 14 or re-install with 17.
Next, I need to remember my GitHub password. Then I can work on cleaning up some tutorials.

And i think you figured already out how to change this (via netbeans.conf) no need to reinstall anything. (technically you don't even have to install NB, just extract and run it) -michael On 23.01.22 04:12, Peter Blemel wrote: I forgot to talk about the JDK! Thanks for that tip. When I first installed NetBeans 12.6, I was using JDK14. I installed JDK17 after installing 12.6 and changed the JDK home to 17. I just changed the JDK home back to 14 and the exceptions go away (but I still can't find my file type in "File -> New"). Do we need to re-install NetBeans to switch JDKs, so that netbeans.conf is correct for the JDK? Thanks, Peter
