Re: Java Generics - "super" keyword usage

Your snippet was really elliptic. I assumed the following definitions:

    interface IColumn { }
    interface ICompactSerializer<T> { }
    class MyColumnSerializer implements ICompactSerializer<MyColumn> { }
    class MyColumn implements IColumn { }

Your problem is that you declare that you are returning a
ICompactSerializer<T> but are actually returning ICompactSerializer<MyColumn>
Even if T somehow is a MyColumn the compiler correctly cannot
figure it out from this context. A cast of MyColumnSerializer
to ICompactSerializer<T> will succeed but is pretty meaningless
w/o knowing what is T.
