The 'shutdown' message simply notifies you that you haven't closed NEWT resources at exit.
Why does the JVM shutdown ?
Because you main method exists and there is no non-daemon thread running,
see our class Animator's API doc (Will copy this to FPSAnimator as well).
* The Animator execution thread does not run as a daemon thread,
* so it is able to keep an application from terminating.<br>
* Call {@link #stop() } to terminate the animation and it's execution thread.

Now main exits, but since the non-daemon thread still operates,
the JVM will not shutdown.

something w/ your X11 setup .. not JOGL related

thats 'normal' and related to Mesa3D's ES/EGL impl.

Anyway you want it :)
You can go as low level as you wish via factories etc
and deal w/ GLContext creation and drawable handling yourself.
However, keep in mind that our managed code path includes lot's
of experience and is an efficient and compatible way of running
GL rendering in a GL*Drawable.
