Here is a test case that, with your patch applied, works differently than JDK 6:
1. Show JFrame with a menu
2. Create a modal dialog with the frame as a parent
3. Dispose the frame
4. Make dialog visible
With JDK 6, the dialog's menu will be disabled. With JDK 8, it will be enabled. So, formally, we've got a regression. I'm not sure whether it is worth fixing, because it looks like a corner case, but still.
