Good morning. What version of NX are you using? The certification tables show that NX10 is the first release to be supported on Yosemite (10.10). NX10 uses Java 1.8 on Mac OS X, so if you are getting a message about Java 6, I would guess you might be using an older version of NX.
Please contact the GTAC Coordinator who submitted the PR for you. He or she can contact the development team who has the PR to see if there is any new information about the issue.
We have done all possible things even escalating the PR has no effect.
Talk to a wall is more slimple then getting a answer.
I guess after a year or so we hear "NX Open Java is no longer suportet on OS X" as answer.
