Kendzi 3D Plugin doesn't work

[MSmolarz]

Hi,
I had JOSM installed as a flatpak until today, but switched today because the "Kendzi 3D" plugin doesn't work in the flatpak. Unfortunately, I don't have an error message for you. Normally a window with the 3D view should open when you start the plugin, but nothing happens. Maybe you can fix this error.

Greetings
Mark

@MSmolarz : This is due to differences between Java 8 and Java 11+.
See #21348, kendzi/kendzi3d#97, and kendzi/kendzi3d#101 .

This is going to be a good chunk of work to fix since the kendzi3d renderer has to be completely replaced. I haven't looked into it yet due to other time commitments, but it probably won't be as easy as replacing JOGL with LWJGL or some other GL library.

JOSM has started including Java in the installers for Mac and Windows, and the included Java for those platforms is Java 16. This will soon be updated to Java 17, IIRC.

Quick update: I have a modification to kendzi3d currently published as kendzi3d-dev. It uses lwjgl instead of JOGL, so it works on more recent versions of Java.
