> Every header.vm calls $site.getMenu(...) to retreive menus for a folder.
> And the class, named 'org.apache.jetspeed.portalsite.impl.PortalSiteRequestContextImpl', manages a set and a map to store and query portlet definition names and menus.
> However, because those are instantiated as a HashSet and as a HashMap, JS2 can throw ConcurrentModificationException when portlet definitions and menus are to be cached.
> This exception can be observed in the following case:
>   - For some reason, user can request twice for the same folder.
>   - For some reason, a developer can design the pages to call header.vm simultaneously.
> (Actually these situations are not usual and it may not occur after first visit for a folder, but it can occur.)
> Therefore, those are to be synchronized.
