 * This annotation can be applied to a package, class or method to indicate that

 * Unless there is:
 * 
 * An explicit nullness annotation
 * 
The method overrides a method in a superclass (in which case the
 * annotation of the corresponding parameter in the superclass applies)
 * 
there is a default parameter annotation applied to a more tightly nested
 * element.
