I tested the proposed package on Lubuntu 17.10.
I tested some example programs they use either:
GLProfile glp = GLProfile.getDefault();
Or they use the GLCanvas default constructor.
Before this version all these examples emitted the typical error found
in the previous version of jogl2. The new package RESOLVED this problem.
I noticed after some experimenting that replacing getDefault with
get(GLProfile.GL2);
also solved the problem. Then I found this thread.
I build scilab from source using the git repository. This is the master
and future 6.1 version it has the same problem. However, scilab 6 and
higher have the jogl2 library prebuild and distributed as a thirdparty
library. Removing this library doesn't work. The problem is that the
scirender module and the gui modules depend on the old syntax. The Java
path in the past was javax.media. In newer version of jogl2 this changed
to com.jogamp. This means that besides removing the faulty library from
scilab the modules scirender and gui need to be patched. I did just this
in the last days. The git master branch version 6.1 build and works with
the new jogl2 version. I noticed however one regression bug the cursor
selection in the plot window work kind of inverted. This is an old bug
which I have seen before.
So, yes this fixes the jogl2 bug. But, no likely not the scilab bug.
Depends how you get scilab and which version probably.

Bug description:
[Impact]
Software that use libjogl2-java (Scilab, Matlab,...) fail to run,
because Mesa dropped 'Gallium' from the renderer string.
[Test case]
Steps to reproduce:
1. have installed Scilab on Ubuntu Xenial system
2. install system updates
3. try to launch Scilab from GUI - it does not start
4. try to launch Scilab from terminal - it does not start with the following
output in the terminal:
$ scilab
Could not create a Scilab main class. Error:

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).
Expected results:
Scilab works normally on Ubuntu 16.04 LTS system.
Actual results:
see error above.
[Regression potential]
The fix is a simple oneliner that allows libjogl2-java to detect Mesa with
both new and original version of Mesa.
