Hello!

Due to technical issues I had today Morning, I had pushed without review following refactoring:
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2019-January/040863.html

Please , accept my aqpologise, and if you can and wish, eyball.

Also if you have any idea how to refactor get_jdk_from_path, please share/contribute/advice.

Thanx !
  J.
