/**
* This annotation can be applied to a package, class or method to indicate that
* the method parameters in that element are nullable by default unless there is:
* <ul>
* <li>An explicit nullness annotation
* <li>The method overrides a method in a superclass (in which case the
* annotation of the corresponding parameter in the superclass applies)
* <li> there is a default parameter annotation applied to a more tightly nested
* element.
* </ul>
* <p>This annotation implies the same "nullness" as no annotation. However, it is different
* than having no annotation, as it is inherited and it can override a ParametersAreNonnullByDefault
* annotation at an outer scope.
