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