Strange Error with web.xml in Spring MVC

I have a strange error with my web.xml, though everything works as intended. Here is the error Eclipse gives:

cvc-complex-type.2.4.d: Invalid content was found starting with element 'load-on-startup'. No child element is expected at this point.

Here is the part of the xml that the error occurs in

<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <multipart-config>
        <max-file-size>10485760</max-file-size>
        <max-request-size>20971520</max-request-size>
        <file-size-threshold>5242880</file-size-threshold>
    </multipart-config> 
    <load-on-startup>1</load-on-startup>
</servlet>

And the error is given on the <load-on-startup>1</load-on-startup>

Is this just a case of Eclipse being strange? Or is there something I am missing?

Here is the full web.xml in case it is something not related to that part of the code at all
