I ran my build-scripts twice with Your patched version using

$ javac -version
javac 1.8.0_05
$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

and

$ javac -version
javac 1.7.0_60
$ java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

just to make sure, both java versions work: I didn't get any errors (well, on my Ubuntu 14.04 development environment). Thank You!

Now, let's wait, and see what is cooking...

Looks good to me too.
