Fix nullability annotations

Eclipse 3.8/4.2 requires that any method which overrides another
method with a @NonNull parameter (see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=381443).

This changeset adds @NonNull on various overriding methods in newly
added code such that Eclispe 4.2 doesn't show errors.
