Yes, I use mesa and set the appropriate environment variable to force the version:

#!/bin/sh
export MESA_GL_VERSION_OVERRIDE=3.1
export CLASSPATH=/home/some_user/dev/jogl/demo/*
java demos.gears.Gears

There are no errors generated/shown (other than not working as intended).  Here is the console output:
