Avery Ching commented on GIRAPH-626:
------------------------------------

These warnings are normal since Unsafe is..well unsafe.  Maybe we can remove the warnings at best?

> I've not looked in to this AT ALL, but I thought I would log it and maybe get the GSoC student (if we get in) to submit a patch to upgrade the offending API usage to fix it. I see this as potentially low hanging fruit for people wanting to contribute to Giraph.
