```
    Description copied from class: DelegatingConnection
    
    If my underlying Connection is not a DelegatingConnection, returns it, otherwise recursively invokes this method on my delegate.
    Hence this method will return the first delegate that is not a DelegatingConnection, or null when no non-DelegatingConnection delegate can be found by traversing this chain.
    This method is useful when you may have nested DelegatingConnections, and you want to make sure to obtain a "genuine" Connection.
