Glassfish AS. In this blog entry, I hope to share some of my initial findings related to role based access control.

Always thought that the Hash implementations (table & map) used buckets that are prime in number. But recently, after digging around the source code to see what that default size resulted in a bit of a puzzling situation...
So let me start with a bit of rambling of my understanding about hashtables.
