SchemaValidation exception when referencing independent schema in wsdl

The following exception takes place on the server when executing webservice with "@SchemaValidation" annotation. Exception does not occur when "@SchemaValidation" is disabled (e.g. able to execute service successfully, client able to run wsconsume, able to access ?WSDL, etc.). A sample application is attached which demonstrates the issue. The webservice being executed (e.g. WSTest.wsdl) does reference another schema (e.g. WSTest.xsd) that defines the input and output arguments to the webservice. Both the WSTest.wsdl and WSTest.xsd schemas are located in the WEB-INF\wsdl directory.
