  • All the native libraries registered by default for lwjgl 2 and 3 in NativeLibraryLoader have the wrong path! (it still works for lwjgl2 and JInput because of this fallback because lwjgl2 and JInput natives are located in the root of the jar)

  • NativeLibraryLoader is never used by jme3-lwjgl3. LWJGL 3 uses its own SharedLibraryLoader so we should remove lwjgl3 libraries from there as it is misleading. Also trying to load lwjgl3 libraries via NativeLibraryLoader won't work anyway and will produce an UnsatisfiedLinkError as it wouldn't find the libraries because of a wrong path.
SEVERE: Uncaught exception thrown in Thread[jME3 Main,5,main]
java.lang.UnsatisfiedLinkError: The required native library 'lwjgl' was not found in the classpath via 'native/linux/liblwjgl.so'. Error message: no lwjgl in java.library.path

  • It does not register the ARM natives for macOS and Linux.
