Hi all,

Bug: https://bugs.openjdk.java.net/browse/JDK-8173145
Webrev: http://cr.openjdk.java.net/~mcherkas/8173145/webrev.00/

The problem appears because AltProcessor doesn't reset altKeyPressed flag when
not-alt key pressed, but event is consumed.
This situation is possible when all events consumed by key bindings. A menubar is activated while
user expects only key binding actions.
In my test a button should be activated by alt+m mnemonic, but a menu is activate, because key pressed/released consumed by mnemonic combination and key typed event is consumed by DefaultEditorKit$DefaultDeyTypedAction that is installed for JTextField,
as result instead of button, menu is activated.

To fix the issue I added resetting altKeyPressed flag if any non-alt key pressed despite consuming state, because obviously user what make some alt+[KEY] action instead of menu activation.

Thanks,
Mikhail.
