The JAXP Schema created through SchemaFactory.newSchema() caches grammars (through SoftReferences [1]) by their schema location. It's been quite awhile since I've looked at how this works, but it wouldn't surprise me if Xerces calls your LSResourceResolver each time you validate in order to give your application an opportunity to redirect the schema location and then use the value returned from the LSResourceResolver to look up the cached grammar.
Thanks.
