Adding to David's comment w.r.t. @throws IAE:

The Class::getXXX APIs returns `Class` or `Class[]` if the result is 
about type(s).  This new `getPermittedSubclasses` returns 
`ClassDesc[]`.   I wonder if this should be renamed to 
`permittedSubclasses` to follow the convention of the new APIs added to 
support descriptors e.g. `describeConstable`

Nit: {@linkplain Class} should be {@code Class}
