There is <test.cxf.version> property to define the cxf artifacts to copy into modules/teststuite/cxf-test/target/embeded folder for org.jboss.test.ws.jaxws.cxf.noIntegration.EmbeddedCXFTestCase.
We need to align this version in cxf version defined in pom.xml and remove the hard code cxf version in test itself.
