Running the IDV with an isl file on a headless server, with command

i.e., including java argument -Djava.awt.headless=true, no longer makes the 
error

ERROR: Creating display master
Canvas3D: null GraphicsConfiguration
java.lang.NullPointerException: Canvas3D: null GraphicsConfiguration

which occured before -Djava.awt.headless=true was used.
(The above command without the
-Djava.awt.headless=true works ok when submitted on a command line).


However now a new error occurs (just below).

Any ideas will be appreciated.
