> The JDBC 4.0 Connection classes implement getTypeMap() by calling
> super.getTypeMap() and copying the resulting map. This is done to prevent an
> unchecked compiler warning that we would see if we simply returned
> super.getTypeMap() in this method. It would be cheaper and simpler to return
> super.getTypeMap() and ignore the warning.
