Yes, JOGL initialization shall bring-up a thread called 'main-SharedResourceRunner'
If a NEWT window/display is open, a thread called 'main-Display-.x11_:0-1-EDT-1'
should be alive.
etc ..
However, these threads are daemon threads _and_
shall be explicitly brought down by our JVM shutdown-hook.
Even if the latter is not working, a daemon thread
shall not hinder the JVM to shutdown.
Maybe JOGL is running in a pre-existing JVM, hence sharing such instance
and is never brought down ?
I tested running single JOGL unit test and JOGL demo applications
from within Eclipse and I could not see remaining JVM instances or threads.
