WS Client does not clean up temporary xsd files.

When running a web services client within JBoss, for each lookup as the WSDL is parsed temporary .xsd files are created under 'server\default\tmp\jbossws' and are not removed until JBoss is shut down.

These files are requested to be created in 'org.jboss.ws.metadata.wsdl.WSDL11Reader'.
