Java 1.6.15, Mac OS X, JMenuItem does not disapear

Question

My application uses some implementation of licensing mechanics. Depending of license type some menu items must be invisible. And now I've run into problem on Mac OS X 10.6.2. Java version 1.6.0_15. Menu items just won't disapear no matter what. I debugged method which implements that functionality and saw with my own eyes - attribute visible becomes false! And there's no code wich could change that in this application. Even more - app works fine on all Windows-es i have with last JRE and on OS X updated to 10.6.8 with Java 1.6.0_31. Is this a buggy Apple's JVM? What is the best solution in such case?

Answer 1

Well, I tried to create SSCCE and failed. In simple subclass of JFrame all works fine. Items disapear as intended. But instead i've found this document. And it says:

Radar #7420583
JMenuItems setVisible(false) do not hide.
Description:
The screen menu bar would not hide JMenuItems that were marked setVisible(false).
Resolution: This issue has been resolved.

As I expected it's Apple's fault. What's left for me is to explicitly check for runtime version on Mac OS X. Any other solutions are welcome in comments(except of upgrading java - it's not my area of responsibility).
