Yes, but as you mentioned the screen menu bar requires a lot of low level AWT integration, and it would be hard to bolt on an alternative implementation after the fact if the underlying model doesn't anticipate such a feature; and it would be silly to fork just to support an alternative menu implementation. So I'm glad to hear you're receptive to the idea.

To be honest, except for the Help menu, I've never perceived the Apple Java global menu bar to be any slower than a native app. Netbeans is the slowest in my personal experience of Java apps I use, but my IDEA menu bar is just as snappy as say, XCode's menu bar. And the Help menu slowdown doesn't seem to be just a Java issue, it's slow period, even in XCode. The first time I click Help in XCode after starting it up, it can take 1-2 seconds before it finally pops up. So I've never thought the Help menu in Java was any worse than for native applications.
Thanks for the reply.
