[CR #422932] Charting does not work properly on Linux machines that do not have X11 installed.
Workaround: Modify the starttomcat.sh script.
Navigate to $SYBASE.
Use a text editor to open starttomcat.sh.
Add the following lines to the file:
CATALINA_OPTS=-Djava.awt.headless=true export CATALINA_OPTS
Save the file and close it.
Restart the application server (Tomcat).
