Michael Bieniosek commented on HADOOP-2325:
-------------------------------------------

Because java 6 (compiler + runtime) is not available under acceptable license on all platforms, I think references to functions like File.getFreeSpace should be done in a way that is backwards compatible with java 5.  I suggest you put all the references to java 6 functions in an optional jar, with fallback methods for java 5 users.

> We should require Java 6 for release 0.16.  Java 6 is now available for OS/X.  Hadoop performs much better on Java 6.  And, finally, there are features of Java 6 (like 'df') that would be nice to use.
