I think that we should adjust it a bit:

respond to the user with unauthorised
I'm not sure using RuntimeException is the best option in this case

private note: yes, the SASL was definitely invalid: lyllcy@tigase.im@tigase.im//lyllcy@tigase.im//<password>

@bmalkow any comments?

Agree. The only change of your proposal is server will respond with invalid_authzid (I think this error code fits better to the case).
