X11Util.Display: Shutdown (JVM shutdown: true, open (no close attempt): 2/2, reusable (open, marked uncloseable): 0, pending (open in creation order): 2) X11Util: Open X11 Display Connections: 2 X11Util: Open[0]: NamedX11Display[:0, 0x7f1f08004b30, refCount 1, unCloseable false] X11Util: Open[1]: NamedX11Display[:0, 0x7f1f08017c80, refCount 1, unCloseable false] Signed-off-by: Xerxes Rånby <xerxes@gudinna.com>
