Java path dropdown select

What does this MR do and why?

Multiple people have been asking for this for a while time to make folks lives a little bit easier when it comes to selecting the Java path, but this will do as it will detect the versions of Java presently installed in the system for Linux and windows.
The only caveat is on Linux systems will need to have update-alternatives (which will be most distros) and on Windows they need to be using oracle java, otherwise the drop down will just be empty, and they will just need to edit their execution string.
