Java desktop team is working hard to move JDK7 forward.
I am happy to announce that Nimbus Look and Feel has been forward ported to JDK 7.Among all other changes, the latest build #b57
contains the fix for 6591875: Nimbus Swing Look and Feel.
It is a real pleasure to see the Nimbus LaF under "javax.swing.plaf" package! Check it out with the recent JDK 7 binaries.
JXLayer will also be there...
