In the course of trying to deprecate the old javadoc API, I came across the following unsuppressible warnings for importing deprecated items.
Compiling 437 files for jdk.javadoc

The items are notable for being nested items, not top-level items.
Also, since the references are in imports, they are not under the implicit suppression of being in a class which is itself being deprecated.
