        throws JsonParseException, IOException {
    JsonToken valueToken = p.nextToken();
    if ((valueToken == JsonToken.START_ARRAY) || (valueToken == JsonToken.START_OBJECT)) {
        // if the currently read token is a beginning of an array or object, move stream forward
        // skipping any child tokens till we're at the corresponding END_ARRAY or END_OBJECT token
        p.skipChildren();
    }
}

		Object beanOrClass, String propertyName) throws IOException {
	JsonParser jsonParser = ctxt.getParser();
	LOG.warn("Unknown Json property: " + propertyName);
	jsonParser.skipChildren();

	return true;
