The JOGL 2.4 test result is actually positive.

Caught handled GLException: EGLGLXDrawableFactory - Could not initialize shared resources for EGLGraphicsDevice[type .egl, v0.0.0, connection localhost:10.0, unitID 0, handle 0x0, owner true, ResourceToolkitLock[obj 0x6002f1c1, isOwner true, <6ec503b1, 6afa9ab1>[count 1, qsz 0, owner <main-SharedResourceRunner>]]] on thread main-SharedResourceRunner

Caused[0] by GLException: Failed to created/initialize EGL display incl. fallback default: native 0x0, error 0x3008/0x3003 on thread main-SharedResourceRunner

This is an informal notification that EGL, even though available,
was not able to initialize the EGLDisplay.

Otherwise, the X11 GLX support is working for you, giving you GL 1.4 support.

If you desire more GL functionality like GL >= 3.1
for shader development and EGL/ES as well,
feel free to set the environment variable:

export LIBGL_ALWAYS_SOFTWARE=true

which should force Mesa3D (the underlying GL implementation) 
to use the software driver.

Please reply with your results and you may set the status to resolved or invalid or worksforme.

test with LIBGL_ALWAYS_SOFTWARE=true

Here is the test output with LIBGL_ALWAYS_SOFTWARE=true. Should I see any difference? The error still occurs and the GL Version still shows as 1.4.

Also, is there a way to disable EGL so as to avoid the error? (And, what features are we missing by not supporting EGL?)

JogAmp 2.4.0-rc-20191231 
https://jogamp.org/deployment/archive/master/gluegen_921-joal_647-jogl_1485-jocl_1128/

As shown <http://forum.jogamp.org/JogAmp-2-4-0-rc-20191231-tp4040215p4040219.html>

Some manual bring-up tests, trying to answer
some of the latest reported 'doesn't work' posts.

Latest build does work on OpenJDK 8 - 14
and Ubuntu 18 - 19.

Even w/ disabled EGL and GLES2 native libraries on Ubuntu 18.04, see below,
the bring-up tests succeed well.

   43  cd /usr/lib/x86_64-linux-gnu/
   44  ls -la libEGL* libGLESv2.so.2*
   45  mkdir nope
   46  mv libEGL* libGLESv2.so.2* nope

Thereby closing this issue for now as in 'works for me',
but we can continue the debate here of course.

Notable here, I ran Ubuntu 18.04 amd64 via virtualization using
a GNU/Linux Debian 10 amd64 host and 
KVM/qemu virtualization.

The GPU Rendering is all done in software, as no hardware acceleration is supported w/ said virtualization.
