GL2 -> profileImpl GL3bc !!! not mapped

[jzy3d]

Somehow JOGL can't map an implementation to the OpenGL version it does detect. Looking for GL3bc means JOGL assume your hadware supports OpenGL 3 and is in backward compatible mode.

Debugging

• Run glxinfo command on the terminal to check which OpenGL version your hardware claim.
• Call GLProfile.getMaximum(true) instead of GLProfile.getDefault() OR GLProfile.get("your OpenGL version") (which is definetely not portable but at least help understanding your situation).
• There is an option to avoid entering the backward compatible mode which is : -Djogl.disable.openglcore=true this partially resolved the problem for me some time ago.

Useful discussions in forum

• Profile not mapped
• Erroneous implementation selection

Julien proposed a fix that worked : You have to replace in GLProfile.java:

} else if(GL2 == profile && hasAnyGL234Impl && ( desktopCtxUndef || GLContext.isGL2Available(device, isHardwareRasterizer))) {
            return desktopCtxUndef ? GL2 : GLContext.getAvailableGLProfileName(device, 2, GLContext.CTX_PROFILE_COMPAT);

by:

} else if(GL2 == profile && hasAnyGL234Impl && ( desktopCtxUndef || GLContext.isGL2Available(device, isHardwareRasterizer))) {
            return desktopCtxUndef || (GL3bc == GLContext.getAvailableGLProfileName(device, 2, GLContext.CTX_PROFILE_COMPAT) && !GLContext.isGL3bcAvailable(device, isHardwareRasterizer)) ? GL2 : GLContext.getAvailableGLProfileName(device, 2, GLContext.CTX_PROFILE_COMPAT);
