> In BetterGfacImpl.java, job submission protocol is being checked as part of
> data movement protocol setting. I believe you want to check if the data
> movement protocol is null. Also, the .get(0) will throw an NPE if you don't
> check that the getHostPrioritizedDataMovementInterfaces() has at least one
> element (in this case I'm checking for not null && not empty).
> Likely, similar code should be applied to the previous .get(0) in the job
> submission protocol previous to this block.
> Here's the patch as a simple diff -u
