Loading multiple beans.xml with XmlWebApplicationContext

[zollen]

In my web.xml

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			/WEB-INF/simple-servlet.xml,
                        /WEB-INF/simple-dao.xml,
                        /WEB-INF/simple-utilities.xml
		</param-value>
</context-param>
	
<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
</listener>

It seems loading multiple bean definition XML files does not work the way I expect. The last loaded XML file seems to overwrite all previous loaded XML files. In above example, the simple-utilities.xml would overwrite all other definitions defined in simple-dao.xml and simple-servlet.xml. Another word, anything defined in both simple-dao.xml and simple-servlet.xml disappear after simple-utilities.xml is loaded, or may be there is a bug in the XmlWebApplicationContext that prevent multiple bean definition files from loading properly.

I am using the latest stable spring 3.0 release. (This is not an issue with Java base Config. @Configuration annotated class can successfully load multiple xml files)
Is this a correct behavior?
