> An unauthenticated client sends any request carrying a _pagedResults_ control (*OID* *1.2.840.113556.1.4.319*) whose _controlValue_ *OCTET STRING* is empty (*04 00*).
> _StoreControlValue_ passes _null_ to _PagedResultsFactory.decodeValue, ByteBuffer.wrap(null)_ throws *NPE* out of the decoder, and the connection is torn down through the generic exception path.
> The same trick works against clients via response controls and zero-length extended-operation values.
