It seems to me an old version of JAXB/xjc tool is on the stack. com.sun.tools.xjc.GrammarLoader, or GrammarLoader.java for example, doesn't exist in JDK7/jaxws. The issue was that GrammarLoader.java used SchemaConstraintChecker that called into JAXP internal classes directly. XMLSecurityPropertyManager was therefore not initialized properly. SchemaConstraintChecker.java in JDK7 has been changed to use SchemaFactory. So I would suggest that while updating to 7u40, the xjc tool should also be updated to a newer version that's compatible with 7u40.
