Yup this refers to Xerces because of the internal implementation of URI (org.apache.xerces.util.URI).
Basically it doesn't handle jar URI's which are in the form of: jar:<url>!/{entry}
In the case of:
jar:embeddedzipfile:file:/home/cprowse/data.zip?lib/config.jar!/repository.xml
it should ignore the query string (?lib/config.jar) as it is part of the url (before the "!/"). This is what the JDK's version of URI appears to do.

Does this question have anything to do with Xerces?
I would expect a query string in a jar: URI to cause problems. To form a URI out of a base URI and a relative URI, the query string and/or fragment identifier should be stripped, the URI truncated at the final / and the relative URI processed (in this case, appended). AFAICT, you should have wound up with a URI of:
jar:embeddedzipfile:file:/home/cprowse/repository.dtd
The result you claim is surprising, but your example is suspicious. How did 'repository.dtd' become 'repository.xml'? Why did you cast base to URI?
