Class WebSocketProtocolException

Thrown by WebSocketDecoder when a frame's declared payload length violates RFC 6455 section 5.2 (the reserved high bit of a 64-bit extended length is set, or the declared length exceeds MaxValue and can never be buffered as a single in-memory frame), or when it exceeds the caller-configured per-frame payload limit (RFC 6455 section 7.4.1, close code 1009).

Raised the moment the declared length is known - before any of that frame's payload bytes are copied into the decoder's reassembly buffer - so an attacker who declares an oversized length and then trickles bytes in slowly cannot force unbounded buffer growth while the decoder waits for a frame that will never legitimately complete.
