> The ActiveMQServerImpl sessions field is a ConcurrentHashMap. Synchronizing
> on the ActiveMQServerImpl object to iterate over the map is not necessary.
> ActiveMQServerImpl#getSession, ActiveMQServerImpl#removeSession and
> ActiveMQServerImpl#createSession also work on the sessions field without
> synchronizing on the ActiveMQServerImpl.
> Removing the synchronized keyword on the ActiveMQServerImpl#getSessions()
> methods e.g. improves loading of Connections view, especially when multiple
> administrators are using the UI.
