Re: Clearing a cache ??

I'm not quite sure why the Cache.clear() method is marked as protected. 
It's been like that since before my time so I don't know what the 
original reasoning behind that decision was, but I can't see why it 
shouldn't be exposed. Generally people just use the flushAll() method to 
mark everything in the cache as invalid instead

I'll take a look and see what the consquences are of exposing this 
method. There may be concurrency problems that need to be addressed, 
since the only place it is used at the moment is from the relative 
safety of the HttpSessionBindingListener.valueUnbound() event handler.

I've created a Jira issue for this, see CACHE-68.
