Yes that's the case.  I see some clarification would help.    I added the following in the spec of `classData` and `classDataAt`:

     * <p> A hidden class created by {@link Lookup#defineHiddenClass(byte[], boolean, Lookup.ClassOption...)
     * Lookup::defineHiddenClass} and non-hidden classes have no class data.
     * {@code null} is returned if this method is called on the lookup object
     * on these classes.
