I want to define the following class as such:

public class CollectionAttribute<E extends Collection<T>> {
    private String name;
    private E value;
    public CollectionAttribute(String name, E value) {
        this.name = name;
        this.value = value;
    }

    public E getValue() { return value; }

    public void addValue(T value) { value.add(T); }
}

This won't compile (cannot resolve symbol T). If I replace the class declaration with the following:

public class CollectionAttribute<E extends Collection<?>>

Then I can't reference the parametrized type of the collection. Am I missing something or have I reached a limitation with generics in Java ?
