-----------------------------------------

yes there's a type, different types but the same name.

> A type mismatch when using side outputs causes a ClassCastException to be thrown. It
would be neat to include the name of the OutputTags in the exception message.
> This can occur when multiple {OutputTag}s with different names but identical names are
being used.
