> official support for compiling on GWT 2.8
> -----------------------------------------
>
> Key: MATH-1406
> URL: https://issues.apache.org/jira/browse/MATH-1406
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Michael Borcherds
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> Is there any interest in allowing Apache Commons Math to be officially
> supported on GWT?
> With GWT 2.8.0 the changes needed aren't too hard to get most of it to compile
> You can see the diff from 3.6.1 here:
