Issues running SwingNodeJDialogTest on Linux

[Kevin Rushforth]

Hmm. That's odd. you could pass "-Djdk.gtk.verbose=true" and see what's 
happening on the GTK loading side. Both AWT and JavaFX will print some 
info if that system property it set.

To find out where the test process is hung you can use "jstack PID". If 
the test itself is hung, then that test would be a good candidate for 
adding a timeout parameter to the "@Test" tag.
