66c52c8826 Revert Java 1.8 changes. Buildable with Java 1.7 
There are still active users on Java 1.7, so building with Java 8
was a no-no. This change reverts the recent migration to Java 8,
allowing JDK 1.7 to compile the code.

This means, at least for the time being, no more Lambda expressions
(Boooooooooooooooo!!)
