As noted in a discussion on the dev list between myself and Andy this update is to rename the current UpdateDeniedException to AccessDeniedException and extend it from a newly created OperationDeniedException.
AddDeniedException and DeleteDeniedException will extend AccessDeniedException.
jena-permissions will extend AccessDeniedException to create:
ReadDeniedException – for read restrictions
UpdateDeniedException – for update restrictions (modifying triples that already exists as opposed to adding new triples)
This will allow Fuskei to properly respond to the case where jena-permissions is in place and there are update restrictions in place. Currently Fuseki returns this as a 500 error. Once we have a common permission denied exception we can return either authentication required or access denied as appropriate.
