22 * Thrown when handshake processing failed to complete due to an internal, unrecoverable
23 * error. This implies a server error (HTTP status code 500) as opposed to a failure in
24 * the handshake negotiation.
25 *
26 * <p>By contrast, when handshake negotiation fails, the response status code will be 200
27 * and the response headers and body will have been updated to reflect the cause for the
28 * failure. A {@link HandshakeHandler} implementation will have protected methods to
29 * customize updates to the response in those cases.
