Thanks Randy,
I modified catalina.sh file inserting
if [ -z "$CATALINA_OPTS" ] ;
then CATALINA_OPTS="-Djava.awt.headless=true" #### headless support
fi ..
restarted the server and I get the following exception:
java.awt.HeadlessException

java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:121)

Please respond to support

I haven't tried it, but this should work. The -D option is just
like the -X options that people use for setting the heap memory. Add it to
CATALINA_OPTS (or TOMCAT_OPTS for those running TC3), restart and you
should
be running just fine.
