Modern Java implementation of Blackboard Pattern?
<p>Is there room for a practical modern application in Java of the <a href="http://www.vico.org/pages/PatronsDisseny/Pattern%20Blackboard/" rel="nofollow">Blackboard Pattern</a> detailed in <strong>"The Pragmatic Programmer"</strong>? Is there any particular library that attempts to assist in the implementation of this concept? What is the general consensus on this pattern in the present software community (especially Java)?</p>

<p>Though the idea is intriguing, I have a feeling that this portion of the book may be outdated.</p>
