This class is used to communicate a SaslAuthenticationException in a way that also signals that any logging
has already been performed, and should not be done again in the delegating class.
Specifically, the
JaasServerOauthOverPlainValidatorCallbackHandler class delegates token validation to
JaasServerOauthValidatorCallbackHandler class which upon failed validation already logs the exception.
When OAUTHBEARER is used, the
getMessage() method is invoked by
OAuthBearerSaslServer, and the message
is included in server response to the client.
