Bug#1068172: gpsprune: 3d function fails with java 17 due to missing "add-opens"

[activityworkshop]

Package: gpsprune
Version: 23.2-1~bpo12+1
Severity: normal
X-Debbugs-Cc: debian at activityworkshop.net

Dear Maintainer,

GpsPrune uses Java3D for the 3d visualisation functions.  Java3D in turn uses class in sun.awt.
Using Java 11, everything works as expected, but using Java 17 introduces restrictions on
package visibility.  Without adding an exception to allow this access, GpsPrune's call to
Java3D fails with an IllegalAccessError.

How to reproduce:
Open GpsPrune (using Java 17), create a pair of points (or load a track) and start the 3D function.
Press 'OK' and the function fails with the message:
java.lang.IllegalAccessError: class javax.media.j3d.X11NativeConfigTemplate3D cannot access
class sun.awt.X11GraphicsConfig because module java.desktop does not export sun.awt
to unnamed module

Modifying GpsPrune's Manifest to include an "Add-Opens" statement does not solve the problem,
presumably because it's not GpsPrune which is trying to access sun.awt.  Adding such a
statement to Java3D's manifests also does not solve the problem, presumably because it's the
GpsPrune jar which is the main jar being executed.

I don't know if this is the best solution, but one way I found to allow access is to add
a parameter to the launch command:
--add-opens=java.desktop/sun.awt=ALL-UNNAMED

Perhaps the Debian maintainers have already dealt with this issue in other packages which
use Java3D, or other occurrences of this module access problem with Java 17?
Many thanks!
