I guess some attachments have the same date, thus they overlap in the
hashmap. Try this:
#set($attachmentsMap = $util.hashMap)
#foreach($a in $attachments)
#if(!$attachmentsMap.containsKey($a.date))
#set($discard = $attachmentsMap.put($a.date, $util.arrayList))
#end
#set($discard = $attachmentsMap.get($a.date).add($a))
#end
#set($dates = $util.arrayList)
#foreach($date in $attachmentsMap.keySet())
#set($discard = $dates.add($date))
#end
#set($dates = $util.sort($dates))
#set($dates = $util.reverseList($dates))
#set($attachments = $util.arrayList)
#foreach($date in $dates)
#set($discard = $attachments.addAll($attachmentsMap.get($date)))
#end
