wsgen creates the bootclasspath for launching APT using the urls of the jars obtained with a getResource on EndpointReference.class and XmlSeeAlso.class. These result in the jdk rt jar when running with JDK6 and in the jaxws/jaxb api jars in deploy when running with JDK5. The latter ones of course use vfszip and this cause the jaxb-xjc code to raise an exception.
