Description Sven Gothel 2025-06-30 12:52:34 CEST 
It has been reported 
<https://forum.jogamp.org/Jogl-2-5-0-on-Pi3-with-Bookworm-Monitor-Name-causes-JVM-crash-td4043589.html>

that `Java_jogamp_newt_driver_x11_RandR13_getMonitorDevice` causes SIGSEGV on
* Raspi 3B+
* jogl 2.5.0
* java 17 (openjdk from apt)
* Raspian Bookworm with kernel 6.6. (July 202) 
* Wayland/Wayfire

"I think i might have found the underlying issue, Raspbian Bookworm uses Wayland/Wayfire as the default window manager. As far as I could find out, Wayfire does implement X11 api, but it might be a bit different in how it returns things. "
