   > looks good, some remarks:
   > 
   > * volatile could be removed again if the Set is made final (and cleared + 
reused in loadBannedIps())
   > * loadBannedIpsIfNeeded is only called with forceLoad set to false -> 
opportunity to be simplified.
   > 
   > sidenote:
   > I noticed that the IPBanList is indirectly polling the modification time 
of the file via isBanned(). Maybe it could be polled only once per second? I 
don't know the exact requirements for this feature however. Maybe @snoopdave 
could help.
   
   Even once per second seems a bit excessive.
