I've run into this exact same problem with Xerces-J 2.x (not a Jakarta project but it is a major "world-wide" jar).
The problem I had was this: A 3rd party company that we partner with uses Xerces, fair enough and so does our software. When using this 3rd party s/w we are stuck with the older version of Xerces they ship with because of some API they use. This is just a different version of DLL hell. Having a different jar name does not solve anything it is just informative. I suppose this is why we see more and more large apps shipping with repackaged versions of components like Xerces and Xalan.

Just think of a 1.x version and a 2.x version having the same package and class names, but different method sets or even different semantics. Now in a large project a piece of software from one vendor needs 1.x and another one needs 2.x. Now consider they really need to share the same class loader and you are lost. You would not if you could have both 1.x and 2.x usable at the same time. Daniel's proposal would make this possible.
