In my case, migrating a Spring 3.1 app up to 3.2.7, my solution was similar to Matthias's but a bit different -- thus why I'm documenting it here:

In my POM I found this dependency and changed it from 6.0 to 7.0:

    
        javax
        javaee-web-api
        7.0
        provided
    

Then later in the POM I upgraded this plugin from 6.0 to 7.0:

        
            org.apache.maven.plugins
            maven-dependency-plugin
            2.1
            
                
                    ...
                    
                        ...
                        
                            
                                javax
                                javaee-endorsed-api
                                7.0
                                jar
