Barracuda: understanding classloading in Java2 (I highly recommend reading this!!!)

With all the classloading issues we've had in Barracuda, XMLC, and Xerces 
and after having solved a number of these issues, I still didn't fully 
understand how the solutions I was using were actually solving my 
classloading problems.  I found a whitepaper that explains these issues and 
I now have a pretty good idea of most of the issues involved.  It explains 
why My current patch to Xerces DOMParser.java (posted on the XMLC list) 
fixed issues in the XMLC-2.2alpha demo app with Xerces not seeing XMLC when 
Xerces existed in a parent classloader (such as shared/lib in Tomcat).

I highly recommend reading this paper.  It doesn't take that long and isn't 
obtuse like some whitepapers I've seen.  In addition, it contains working 
examples described in the paper.
