Description

When activating schema validation webservice calls fail with an AssertionError, because the Weblogic DOM-implementation uses AssertionErrors to mark unimplemented methods instead of Exceptions.

W3CDOMStreamReader "only" catches all Exceptions when using Node.getUserData.

From org.apache.cxf.staxutils.W3CDOMStreamReader starting with line 413:

    public Location getLocation() {
        try {
            Object o = getCurrentNode().getUserData("location");
            if (o instanceof Location) { 
                return (Location)o;
            }
        } catch (Exception ex) {
            //ignore, probably not DOM level 3
        }
        return super.getLocation();
    }

Since Weblogic uses an AssertionError, the DOM Level is not correctly detected and the Error is not catched:
