Build Java Plugin with Java 1.7 instead of 1.6 which is default on some distros

Java SE 6 Premier support end on Dec 2015. And recently Jenkins server requires Java 7. So all our build systems will have Java 7. It will be reasonable to build HPCC Java Embeded Plugin wiht Java 7 even though some Linux distro has Java 6 as default, such as Ubuntu 12.04 and CentOS 5/6.
