In bug 35706 I asked for UpstreamVersionFreeze exception for gossip 0.10.2 - this includes the following fix
"- Changed the account ID for Jabber IDs back to 'username@server' and
make the resource a separate entity in the accounts.xml (note: there
is some extra code to make sure the same problems that occurred last
time don't reoccurr this time with invalid usernames when trying to
connect) (Martyn). "
That one will hopefully make the world happy again. I'd be grateful, if you could check, once it's in the archive.
