Thomas, Thanks a lot for your responses.
I made a change in my Ant build GWT Compiler by adding the line (text in
green) as you suggested to my <java> task; I copied my build.xml code.
I also copied the error below I am getting after adding this sysproperty.
Can you please check the error and suggest next steps ?
