Scilab cannot create Scilab Java Main-Class (we have not been able to find
the main Scilab class. Check if the Scilab and thirdparty packages are
available).

I checked my MESA info with glxinfo:

chris at eniac:~/scilab-branch/bin$ glxinfo|grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: AMD OLAND (DRM 2.50.0 / 4.15.0-36-generic, LLVM
6.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.0.5
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 18.0.5
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 18.0.5
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
OpenGL ES profile extensions:

Using the command with MESA_GL override = 3.0 :

chris at eniac:~/scilab-branch/bin$ export MESA_GL_VERSION_OVERRIDE=3.0 ;
~/scilab-branch/bin/scilab 
scilab-bin: error while loading shared libraries: libgfortran.so.3: cannot
open shared object file: No such file or directory

So back where I was yesterday.

I checked your suggestion of the graphics issue and installed the
proprietary AMD driver for my graphics chipset ( an R7 240 , getting
slightly long in the tooth) and received the following error:

amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only
compatible with 3.x.x.

So maybe I need to get a new graphics card.

I'm going to check if its better on a reboot but wanted to c&p all my
console responses here first before I did so.
