Subject [jira] [Commented] (GIRAPH-847) Add back java 6 source compatibility
Date Sat, 15 Feb 2014 00:06:22 GMT

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).

> 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.
