> If {{UGI.getGroupNames()}} catches an IOE raised by {{groups.getGroups(getShortUserName())}} then it simply logs @ debug "No groups available for user". The text from the caught exception and stack trace are not printed.
> One IOException raised is the explicit "user not in groups" exception, but there could be other causes too —if that happens the entire problem will be missed.
