Screaming Penguin - Source Does Matter

As you all know Jakarta is a project of the Apache Software Foundation, focused on
delivering high quality open-source solutions based on the Java platform.

Jakarta is best know for their Tomcat application server but also for Ant,
which is an excellent build tool that recently won the JavaWorld Editors'
Choice Award for Most Useful Java Community-Developed Technology.

However, Jakarta is also home of other, not so widely known projects.
One of them is Collections package, part of Jakarta Commons project which extends Sun's Java Collections Framework.

On March 05 Jakarta released version 2.0 of Collections. This new release provides several new collections
including Bag (a.k.a multiset) and DoubleOrderedMap (map based on red-black tree). It also introduces several new, useful comparators.
I wonder if Jakarta Collections package will eventually be incorporated by Sun in J2SE 1.5.   Jakarta Commons
