jodygarnett comments:

So when running in Java 17 a bunch of configuration is required - to ask Java to "relax" all the safety measures that were introduced. As an older application GeoServer likes to do some unsafe things, like provide a new rendering engine, or make use of an image processing engine called "javax.media.JAI" that was initially written as an extension of core Java. Since Java 17 is not so supported yet, the documentation is not "handy" for me to tell you what to do ...

Maybe try this: ​https://docs.geoserver.org/latest/en/user/production/java.html#running-on-java-17

Fixed, since we upgraded to GeoServer 2.26.0 which works fine with Java 17.

[jive]

So is this fixed now? Do the layer demos work?

aside: Note the first time you run such a thing the results may be blocked as a pop-up depending on your browser settings.

It needs either a full rewrite or to be removed... I'd go for the latter, what say you jodygarnett (Jody Garnett) ? it's part of the data dir, which I'm guessing is not something you touch when upgrading GeoServer. I'd recommend removing it from OSGeo live. Making a stand alone demo based on a modern OL version is likely a better proposition, assuming anyone shows up to work on it
