jackson-core: UTF8DataInputJsonParser._reportInvalidToken() missing maxErrorTokenLength limit -> unbounded StringBuilder growth (DoS)

Status FULLY REPRODUCED. A malformed token fed through createParserDataInput produced a 20,000,109-character exception message from a 20-million-character attacker payload, while the identical payload fed through createParserInputStream produced a correctly bounded 367-character message. Affected...
