Yeah, Gwt should optimize them in compiler time, but at the end the
optimization will produce arithmetic operations with javascript String
implementation, and this optimization will penalize the time spent to
compile.
So why use StringBuffer instead of String unless this code was shared
in both

but if I understood you correctly you said there was a client side
