"The following addresses failed" on localhost

You are trying to create an EntityBareJid from the String ‘me’, which does not represent a valid entity bare JID and thus fails. JIDs always have a domainpart, e.g. me@example.org

Your SSLContext is unable to establish a trust path to the certificate presented by the XMPP service.

You are welcome.

I am always happy about user feedback, in order to improve the API and make it more user firendly, so feel free to keep it coming. Please note that there is also a MUC smack@conference.igniterealtime.org where you can ask questions. I am usually around, and if I have time, I am glad to help (But I do not provide unpaid 24/7 support obviously ;)).
