I am trying to make a method call like this,

public class GenericsTest<T> {

    public static <T> Map<String, T> createMap(Class<? extends Map<String, T>> clazz) {
        return null;
    }

    public static void main(String[] argv) {
        Map<String, Integer> result = createMap(TreeMap.class);
    }
}

But I am getting this error,

<T>createMap(java.lang.Class<? extends java.util.Map<java.lang.String,T>>) in test.GenericsTest<T> cannot be applied to (java.lang.Class<java.util.TreeMap>)

How to fix this problem?
