At a quick glance, my guess would be the issues are around
GLRendererQuirks.GLNonCompliant which would be set with detected mesa driver
and requested (compatCtx && (major > 3 || (major == 3 && minor >= 1)).
It would then refuse to use such contexts.
(I would tend to think it is a bug in jogl somewhere with different gl versions
being available for core/compat contexts but I have no idea really.)
