Image upload error -- thumbnails aren't being generated

[GoogleCodeExporter]

Whenever we upload an image (JPEG or PNG, I haven't tried other file types) we 
get a Javascript error:

--------------------------------------------------------------------------
There was an error on this page.

Error description: TypeError: document.getElementById("file_added") is null

Click OK to continue.
--------------------------------------------------------------------------

The image file is uploaded and (after a refresh) will appear in the folder to 
which it was uploaded, but there's no thumbnail.  Our log shows an error 
(attached) that makes it look like IR+ is trying to do something with X11, 
which is bizarre!

We haven't seen this issue on our UNIX environment - looking into the issue 
this may solve the problem.  

Try putting this in your ${CATALINA_HOME}/bin/catalina.sh script:
export JAVA_OPTS="${JAVA_OPTS} -Djava.awt.headless=true"

tomcat will need to be restarted after the changes are made

As a possible long term non tomcat configuation change - I have added code to 
initialize this property in the code as well.  Testing will need to be 
completed.  Will be added to the 2.x or 3.x release
