Ok, I understand the problem now. The thing is that Tomcat will now refuse to load the JAXP base classes from the webapp repositories. There are lots of problems with JAXP overall, so I prefered to avoid the classcasts problems, which didn't have any clean workaround. Here, it's very easy to fix (don't worry, having Xerces or jaxp.jar in server/lib won't create any more classloading problems :)). Sorry, the bug report you filed was incomplete, so the explanation I put in there was not the right one.
