IQ type="result" getting java.lang.IllegalArgumentException
Current development version hitting these two issues related to not routing IQ result stanzas
Updated affected IQ handlers to ignore error and result packets.
From LocalMUCUser.process(IQ packet)
so the comment doesn't match the actual code. Which appears to would fix the problem.
IQPingHandler just seems to miss the IQ type check completely, i.e. there is no need to reply to an IQ not of type set or get.
