Mac OS X 10.10 (Yosemite) Java Swing Look and Feel?

Question

When I launch a java application using Swing for the GUI, I notice on Mac that Swing still renders the "old" Mac UI (10.9 and older). Since Oracle is now responsible to write the JRE for Mac OS X - where can I find any new UI?

Or are there any alternatives out there?

Answer 1

This spiked my curiosity since it also bothers me.
@MadProgrammer appears to be correct. Acoording to the Oracle's page about Look and Feels, HP, IBM and Apple provide their own Look and Feels. To my understanding, this clears Oracle's responsability over the out of date L&F, and transfers it to Apple itself.
The only foreseeable option is to wait for updates...
