Hello

I'll have to modify https://jogamp.org/cgit/jogl.git/tree/make/config/jogl/gl-gl4bc.cfg in order to use GLContext to know whether glLoadTransposeMatrixd and glMultTransposeMatrixd are broken and to use the suggested workaround in this case. Actually, I'll have to implement something a bit different to make it work when you call glMultTransposeMatrixd or glLoadTransposeMatrixd alone, I will probably convert the 4 × 4 row-major matrix into a  4 × 4 column-major matrix and call glMultMatrixd. I'll write a bug report.
