Sounds like you could just keep it around for 30 minutes or an hour, refreshing it after it expires.
What would be nice is to be able to perform the refresh asynchronously. Say it takes 5s to build a piece of data that every appserver uses for practically every request. Instead of relying on memcache, it would be nice to just keep this as static/application-scoped data in the appserver - and have a cron job that updates every instance every 15 minutes or so. This is easy to do if I can create threads, and a common pattern in the JavaEE world.
