Avery Ching commented on GIRAPH-847:
------------------------------------
Ah, I see. That is very unfortunate. There are quite a few Java 7 features
beyond these simple things.
Here are a few examples:
http://en.wikipedia.org/wiki/Java_version_history#Java_SE_7_.28July_28.2C_2011.29
Java 7 is additionally more performant than java 6.
Many projects have already moved to Java 7 (i.e. Hive -
https://issues.apache.org/jira/browse/HIVE-4583).
> Add back java 6 source compatibility

> Key: GIRAPH-847
> URL: https://issues.apache.org/jira/browse/GIRAPH-847
> Project: Giraph
> Issue Type: Wish
> Components: build
> Affects Versions: 1.1.0
> Reporter: Craig Muchinsky
> Priority: Minor
> Attachments: GIRAPH-847.patch

>
> 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.
