Environment: OSCache used in JSP pages served by Tomcat.
JBoss providing data that we want to cache.

Description:
We're using OSCache to reduce expensive round-tripping between web containers and the EJB container.

We use groups to implement fine-grained cache control, where group names are constructed in a way that identifies the entities from which data was used in cache entries.

When entities change, the entities (running in the EJB container) fire cache flush notifications with JavaGroupsBroadcastingListener.sendNotification().

In this way, all cache entries associated with a changed entity are flushed.  It works wonderfully, and OSCache rocks hard, fast and furious.

The problems are:

1) AbstractBroadcastingListener and descendents declare sendNotification() protected, and

2) ClusterNotification's FLUSH_KEY, FLUSH_GROUP, FLUSH_PATTERN and FLUSH_CACHE constants are package-protected.

This means that we have to graft our own wrapper class into the com.opensymphony.oscache.plugins.clustersupport package and reroll oscache.jar.

Please consider promoting these overly protected members to public.
