Unsupported major.minor version when using 0.5.0 version of VCFComp

Running VCFComp on spark 1.6.0, Java 7 and Scala 2.10 results in this exception:

Probably the new version is compiled against Java 8?

This probably has to do with the Java version used to start the notebook. Better to use Java 8 as suggested.
