[7u4] Request for phase 2 approval for CR 7124321: [macosx] TrayIcon MouseListener is never triggered

Bug:  http://bugs.sun.com/view_bug.do?bug_id=7124321
Webrev: http://cr.openjdk.java.net/~leonidr/7124321/webrev.01/
Review thread: http://mail.openjdk.java.net/pipermail/macosx-port-dev/2012-March/003520.html
Reviewer: Anthony Petrov (anthony)

Rationale for inclusion in 7u4: it's a regression from JDK 6. The fix modifies TrayIcon related code only in a rather simple way, so it's a low risk fix.

Thanks,
Leonid.
