Let's remind the drawable factory hierarchy :

This page is a good explanation of what EGL is w.r.t CGL (macOS) WGL (Windows) and GLX (Linux).

There are existing problems discussed in JOGL forum regarding EGL

The issue initially arised while running DemoTernaryChart3d_withAxisLabels_Native. This will most probably occur while running any demo such as SurfaceDemoAWT on the same Windows 10 computer.

I tend to think that the reason is that MESA appears in the Windows PATH variable, probably due to having installed MESA through MSYS2.

I can get rid of this exception by doing two things

• completely removing MESA from my Windows PATH variable
• edit path to replace MESA by this distribution which is a subset of MESA DLLs
