Thanks for reporting this issue. I’ve logged it as https://issues.igniterealtime.org/browse/OF-1808

Can you tell if more (clustering-related) functionality is affected?

A fix for this problem should be available in the nightly build from July 9th (and later). I’d appreciate someone giving this a test for us! https://www.igniterealtime.org/downloads/nightly_openfire.jsp
