Now I think we are getting to the reason for the issue.
SAXParserFactory is the JAXP way of creating the SaxFactory to be
used. However since you let JAXP determine and figure out the
configuration and the parser to be used, you can run into
configuration issues.
My experience with using JAXP within OSGI based bundles is that you
can get some unexpected results that crop up. There are a couple of
possible solutions.
1. Try setting the setXIncludeAware() method to either true or false
to see if that fixes your problem. You many need to set the other
configuration options as well.
http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/SAXParserFactory.html
2. Call and use the Xerces specific implementations directly, and
setup your configurations.
I personally try to avoid using JAXP within OSGi because of the
unpredictablility when it interacts between bundles.
It may work for a while, and then it just goes nuts one day.

The org.eclipse.jst.jee.util.internal.XmlRootHandler uses
SAXParserFactory factory = SAXParserFactory.newInstance();
while the org.eclipse.core.internal.content.XmlRootHandler uses
Activator.getDefault().getFactory() (our JPT copy uses this
as well)
Will changing our JPT copy to use the former fix this problem? And
if so I don't understand why the problem suddenly cropped up. I
apologize if I seem clueless about this, it's because I am :)

I copied XmlRootHandler from
org.eclipse.core.internal.content.XmlRootHandler and that class has
not changed since 2008. Not really sure how that could have
suddenly caused this problem.

How ever your orm content type is being set up, and where you are
getting your XML parser is causing the issue. The WTP parser is
setup to be an XInclude aware configuration. You can't cast
between these to configurations.
I'd check to see how your SAX based parsing and content resolver
are being setup and configured when calling Xerces. Particularly
check your createParser code.

JPT has a bunch of test failures in last night's build and I am
unsure of the cause. We did release, but I am confused by the
exception (see below) appearing in the log file that are
preventing our xml content types from being loaded. I updated my
target workspace to last night's build and do not have test
failures. Any ideas would be appreciated.
Thanks,
