Note: EGL package has changed due to Bug 1096. 'Java_com_jogamp_opengl_egl_EGL_dispatch_1eglGetConfigAttributes' from 'make/config/jogl/egl-CustomCCode.c' is included into 'build/jogl/gensrc/native/jogl/egl/EGL_JNI.c' via make/config/jogl/egl.cfg's: IncludeAs CustomCCode egl-CustomCCode.c On GNU/Linux: objdump -T libjogl_mobile.so | grep eglGetConfigAttributes 00000000000323e7 g DF .text 0000000000000105 Base Java_com_jogamp_opengl_egl_EGL_dispatch_1eglGetConfigAttributes Method is invoked on GNU/Linux and Android, no crash has been reported. I will double check w/ Windows .. Missing 'JNIEXPORT void JNICALL' in func-decl of make/config/jogl/egl-CustomCCode.c .. hence it never landed into the windows dll validating now .. dc15a430ee28f226e047ddebabf902d4c10b067a:
Fix regression of commit cf1163fc88976e7087d3a17524a49139e35a4708,
i.e. missing function calling convention and return type qualifier
for 'Java_com_jogamp_opengl_egl_EGL_dispatch_1eglGetConfigAttributes':
JNIEXPORT void JNICALL
This lead to its exclusion in the resulting Windows dll.

I'd like to point out that library jogl_mobile.dll, as well possibly the others O.S. flavors, miss the corresponding native version of the following method from jogamp.opengl.egl.EGL.java class: private static native void dispatch_eglGetConfigAttributes(long dpy, long config, int attributeCount, Object attributes, int attributes_byte_offset, Object values, int valuesOffset, long procAddr); When I try to run a demo with GLProfile.GL2ES2 with VM attribute -Djogl.enable.ANGLE=true, I have the following exception stack trace: Exception in thread "main" java.lang.UnsatisfiedLinkError: jogamp.opengl.egl.EGL.dispatch_eglGetConfigAttributes(JJILjava/lang/Object;ILjava/lang/Object;IJ)V at jogamp.opengl.egl.EGL.dispatch_eglGetConfigAttributes(Native Method) at jogamp.opengl.egl.EGL.eglGetConfigAttributes(EGL.java:804) at jogamp.opengl.egl.EGLGraphicsConfiguration.EGLConfig2Capabilities(EGLGraphicsConfiguration.java:221) at jogamp.opengl.egl.EGLGraphicsConfigurationFactory.eglConfigs2GLCaps(EGLGraphicsConfigurationFactory.java:480) at jogamp.opengl.egl.EGLGraphicsConfigurationFactory.getAvailableCapabilities(EGLGraphicsConfigurationFactory.java:210) at jogamp.opengl.egl.EGLDrawableFactory.getAvailableCapabilitiesImpl(EGLDrawableFactory.java:718) at javax.media.opengl.GLDrawableFactory.getAvailableCapabilities(GLDrawableFactory.java:474) at com.jogamp.opengl.JoglVersion.getAvailableCapabilitiesInfo(JoglVersion.java:80) at com.jogamp.opengl.JoglVersion.getAllAvailableCapabilitiesInfo(JoglVersion.java:107) at com.jogamp.opengl.JoglVersion.getDefaultOpenGLInfo(JoglVersion.java:125) at javax.media.opengl.GLProfile.initSingleton(GLProfile.java:218) at javax.media.opengl.GLProfile.getProfileMap(GLProfile.java:2246) at javax.media.opengl.GLProfile.get(GLProfile.java:959) at javax.media.opengl.GLProfile.get(GLProfile.java:975) at gles.tests.RawGLES2demo.main(RawGLES2demo.java:298) The line 298 at RawGLES2demo.java has the following statement: 298 GLCapabilities caps = new GLCapabilities(GLProfile.get(GLProfile.GL2ES2)); Checking the jogl_mobile.dll with PE Viewer is possible to note that above method is missing, in both x86 and AMD64 versions. Checking at Github I note the that the missing functions is available at file jogl/make/config/jogl/egl-CustomCCode.c and possibly generated from file egl-CustomJavaCode.java in the same folder. I guess the make file just missed compile & link operations with above source code. It happens on JOGL 2.2.4 and 2.3. I didn't check others releases
