How dow I implement AffirmativeBased object in Spring Security 4? -

in spring 3, constructor looked this:

public affirmativebased(list<accessdecisionvoter> decisionvoters) 

in spring 4, constructor adds type:

public affirmativebased(list<accessdecisionvoter<? extends object>> decisionvoters) 

can me understand it's looking for?

i facing following exception:

org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type [java.util.list] found dependency [java.util.list>]: expected @ least 1 bean qualifies autowire candidate dependency. dependency annotations: {}

i able fix changing property constructor argument.
