SmackException (and it's subclasses) is for all errors/exceptions not defined by any XMPP specification. XMPPException is now an abstract class for all errors defined by the XMPP specifications. Methods that involve an IQ exchange now either return the result, which is obtained by IQ response, or they throw an XMPPErrorException if an IQ error was the result of the IQ set/get. If there was no response from the server within the default packet timeout, a NoResponseException will be thrown. XMPP SASL errors are now also reported accordingly. SMACK-426
