Looking at the code [1], IMO this is a likely a bug. This is indeed gonna blow up each time the previous build will still be building, as build.getResult() will by contract return null if currently building.
So, I think you should file an issue in the tracker about that. And if possible the associated PR to higher your chances to get an official release with that fix.
