Claudio Martella commented on GIRAPH-847:
-----------------------------------------
I don't think we should stick to java6, but as we're facing 1.1.0, and we are
currently not using ANY of the additions of java7 except for the two lines of
code that Armando is mentioning, it would be worthwhile to just be back
compatible with java6 for this release, and still have java7 as the default vm.
It does not cost us anything, and one can still run giraph in a java7 vm for
performance reasons.
> Add back java 6 source compatibility

> While I understand that java 7 is the default for Giraph now, I suspect there
> are some folks such as myself who are stuck with java 6 for the time being.
> It doesn't seem like Giraph is heavily taking advantage of java 7 features
> yet so it might be nice if the remainder of the 1.x releases keep java 6
> source compatibility (at least for graph-core). By my count there are only 6
> source files in giraph-core that use java 7 syntax.
