Actually, I took your advice and managed to set break points in Chrome's 
Developer tool (in Source tab, under sourcemap folder where the Java 
classes are) and debug from there (not that anything made sense with all 
the generated JavaScripts).

I also tried SDBG which more or less does the same thing but in the Eclipse 
as a plugin. I just followed the video on SDBG site <>and 
got it to work. What was confusing about it was to run debugging in 
SuperDevMode first, then rerun the Eclipse Debug As, but this time Launch 
Chrome from Debug Configuration. It actually spawns two (2) debugging 
sessions from the looks of it: one for Web Application (code server) and 
the other for Launch Chrome. Thanks for the recommendation.
