Kevin Savage updated GIRAPH-638:
--------------------------------

    Attachment: GIRAPH-638.patch

This is a patch against branch-0.1. 

I haven't written a test because there was no test for this class. I have run the job and it allowed us to change the memory.

I suspect that the same change could be made to trunk, but I've not looked at that code yet.
