Schema Validation Fails for Mock Service - cannot use pom.xml workaround

Has anyone found a solution that does not involve pom.xml?  We do not use that.  The xsd:import statement in our wsdl does not contain any ampersands.  SoapUI is rewriting the import specified in the wsdl and adding the unescaped ampersand. This worked fine with Java 6. We noticed the SaxParseException only after upgrading to Java 7 with the same version of SoapUI.
