-----------------------------------------------------------

We should be able to easily address this then.
Just need to determine what default values are available for applicable environments.
We have basically dropped support for java 1.6 - so 1.7 and 1.8 are all what we need to worry about.

[~jeffreyr97] - did you test that with the IBM jdk as well?
