Spring batch admin doesn't start with xsd validation disabled

[d_cavestro]

I've embedded spring batch admin in my web application and disabled xsd validation in order to be able to configure some transaction properties (as per http://forum.springsource.org/showth...xsd-validation ).
But disabling xsd validation it seems that some bean initialization suffers from missing default values: the application doesn't start complaining

Caused by: java.lang.IllegalArgumentException: Invalid log level ''. The (case-insensitive) supported values are: FATAL,ERROR,WARN,INFO,DEBUG,TRACE

Steps to reproduce using the spring batch admin sample module:
* modify the web.xml in order to use a custom class to load the application context from xml
* build the app
* deploy and run
where

	<context-param>
		<param-name>contextClass</param-name>
		<param-value>com.acme.NovalidationXmlWebApplicationContext</param-value>
	</context-param>

is a web.xml snippet needed to use a custom class to load the xml with no schema validation and

package com.acme;

import org.springframework.beans.factory.xml.XmlBeanDefinitionReader;
import org.springframework.web.context.support.XmlWebApplicationContext;

/**
 * XML application context with no xsd validation.
 * 
 * @author Davide Cavestro
 *
 */
public class NovalidationXmlWebApplicationContext extends XmlWebApplicationContext {

	public NovalidationXmlWebApplicationContext () {
		// no-op
	}
	
	protected void initBeanDefinitionReader(XmlBeanDefinitionReader beanDefinitionReader) {
		beanDefinitionReader.setValidating (false);
//the following settings bring to same result: IllegalArgumentException
//		beanDefinitionReader.setValidationMode (XmlBeanDefinitionReader.VALIDATION_NONE);
//		beanDefinitionReader.setNamespaceAware (true);
	}
}

is the class that disables xsd validation.

What's wrong with my configuration?
The main side effect is that my application cannot disable xsd validation and still embed spring batch admin.
