In order to make it available for other L&F's, the getAcceleratedString method and calculateAcceleratedStringSpace method is Implemented in ToolTipUI class. These methods are used in BasicToolTipUI class which uses the feature and shows/paints the ToolTip String along with the set Mnemonic key. In similar way other L&F which doesn't Inherit BasicToolTipUI can make use of the feature available in ToolTipUI.

This will require CSR

I guess this can be removed from here and BasicToolTipUI as it is being defined in ToolTipUI

Although it is being placed in its super class so it can still be accessed
but am still not sure if you can remove this public method from this public class without notifying via @deprecated or @forRemoval tag

Remove @author tag

Since it is supposed to be run on all platforms, this L&F cannot be hardcoded as this will not be applicable/present in all platforms
