Keyboard shortcuts are not displayed in main menu of an application. Can be reproduced with the attached sample J2SE project by running with 7u6 b06 versus with 7u6 b05. The sample project has a shortcut registered for the File / About action. The shortcut is visible with b05 and not with b06.
A regression in 7u6 on Mac. Introduced in b06 and still present in the latest 7u6 b20.
This problem has a critical usability impact on NetBeans users on Mac OS-X.
