NLS @NonNull keys and the link towards messages.properties

In my project, we want to use the externalized strings and NLS mechanisms.
And we want the string constants to be non-null annotated, so it is not needed to use a

````
var msg = MessageFormat.format(requireNonNull(Messages.mykey), value );
````

To achieve this, we tried to have a Builder, that patches the Messages class to be like

````
@NonNullByDefault
class Messages {
public static String myKey = ""; //$NON-NLS-1$
}
var msg = MessageFormat.format(Messages.mykey, value );
````

The initialization with empty string avoid to get errors from the null-analysis.

However, with this initialization, the feature that you can Ctrl-Click on the constant and it jumps to the properties file location does no more work.

Is this a Bug or missing feature? Or is there a completely different approach I can go?
