-------------------------------------------

             Summary: Remove use of deprecated API's in giraph-core

                 URL: https://issues.apache.org/jira/browse/GIRAPH-626

             Fix For: 1.1


When I compile & test the new 1.0 RC0 (great work BTW), I get the following WARNINGs within Maven. 

{code}

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.
