> A client searches a hostile server (or *MITM*'d plaintext session); the server responds with a _SearchResultEntry_ whose attribute-description *TLV* contains _bytes \{0x63, 0xC3, 0xA9\}_.
> Strings.toLowerCase indexes TO_LOWER_CASE_BYTE[-61] and throws AIOOBE, which escapes the decoder as a RuntimeException; application code catching only LdapException mishandles or crashes.
