Review comment:
The other register method gets into reading the annotation on the `UDF`
class looking for its name - for DS functions it will either bump into an NPE
or came up with a completely different name....
This behaviour is really wierd because it have got the udf name as argument.
the `registerDuplicateFunction` only registers the function....I think the
other method should be investigated why it interrogates UDF annotations - I
think the name `registerDuplicateFunction` is an unlucky name...it should be
renamed
