[gwt-contrib] Re: GWT 2.6.1-RC2

Mon, 05 May 2014 08:30:36 -0700 

I ran RC2 in CI over the weekend, and saw 0 issues.  However, today I ran a 
build against a much larger instance size, and a stack overflow popped up. 
:'(

I'm not sure if it's reproducible (runs fine locally and on an aws 
c1.medium), but on aws c3.xlarge:
