2021-10-07 10:36:29.509 java[8248:1160872] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!' 

Found the bug has been fixed in Jogamp on 5 apr 2019, planned for Jogl 2.4.0, not released yet (current is 2.3.2), AMAPstudio is in Jogl 2.2, see this page

1. Unistalled Jogl 2.2 from AMAPstudio:

• from the ext/directory, removed:
  • gluegen-rt.jar
  • gluegen-rt-natives-linux-amd64.jar
  • gluegen-rt-natives-linux-i586.jar
  • gluegen-rt-natives-macosx-universal.jar
  • gluegen-rt-natives-windows-amd64.jar
  • gluegen-rt-natives-windows-i586.jar
  • jogll-all.jar.jar
  • jogl-all-natives-linux-amd64.jar
  • jogl-all-natives-linux-i586.jar
  • jogl-all-natives-macosx-universal.jar
  • jogl-all-natives-windows-amd64.jar
  • jogl-all-natives-windows-i586.jar

• No more .dll / .so to be removed (packaged inside the jars since 2.2)

2. Installed Jogl 2.4 (snapshot gluegen_938-joal_661-jogl_1507-jocl_1148) in ext:

• Followed this doc: https://jogamp.org/wiki/index.php?title=Downloading_and_installing_JOGL

• Downloaded material from here: https://jogamp.org/deployment/archive/master/gluegen_938-joal_661-jogl_1507-jocl_1148/archive/

→ jogamp-all-platforms.7z 2021-01-12 00:35 74M

• Picked and copied in amapstudio/ext/ :

3. Adapted to the move of javax.media packages to com.jogamp

Concerns javax.media.nativewindow and javax.media.opengl. Jogamp team moved them to com.jojamp.nativewindow and com.jogamp.nativewindow

See this discussion thread: https://jogamp.org/bugzilla/show_bug.cgi?id=682

In Eclipse, updated the jar list in amapstudio project build path, then selected amapstudio/ and Ctrl-Shift-O to reorganize all imports to point on the com.jogamp pakages

4. Last jogl snapshot is gluegen_938-joal_661-jogl_1507-jocl_1148, tryied it but failed at execution / compilation time: was compiled with java 11

• java.lang.EnumConstantNotPresentException: javax.lang.model.SourceVersion.RELEASE_11
• found a message on july 2012 telling joamp switch to java 11 was a wip (work under progress)

5. Tried to find an older Jogl snapshot with the bug fixed and still in Java 8…

• searched a snapshot after correction (apr 2019) and before switch to java 11
• tried gluegen_916-joal_642-jogl_1483-jocl_1122 (10.4.2019)

Same compilation error, also in Java 11.

→ correction in not possible in Java 1.8

→ Oriented Thomas Arsouze on workaround found with Francois Pimont :

Problems were reported when using Capsis or AMAPstudio under Mac OS X.

'Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!'', Camilo Valdes, 21.10.2020, Francois Pimont, 1.9.2020, this could be fixed by switching from Java 1.8.0_261 to Java 1.8.0_202.
