> https://github.com/apache/jspwiki/pull/234
> Replaces java.util.Vector with ArrayList or a concurrent collection,
> depending on how each list is accessed. Lists that are iterated while other
> threads modify them (ACL entries, ACL entry permissions, group members and
> the SpamFilter ban list) use CopyOnWriteArrayList. Lists that are only
> touched while holding their owner's lock (the WikiEventManager preload cache
> and the SpamFilter modification list) use a plain ArrayList. The
> jspwiki-xmlrpc module is left unchanged, because the XML-RPC library it uses
> requires Vector. The jspwiki-main tests pass. There is no new test for the
> concurrent access.
