<@U0F8Y5E5A> you have an eye for subtle code nuances. Any ideas?

thomasnield: Me? Why me? :slightly_smiling_face:

Anyway, I would start with getting line where this `SQLException` occurs.

As you are using the `subscribe` without, `onError`, it doesn't really say where it's wrong.

I'd guess it's in the middle of executing `mapping` when `close` is called.

If close was called that should throw a ResultSet Closed

Exhausted Resulset is thrown when you don't have more rows and try to read

So unless the table is empty or some other problem with the database, what is happening is that you are reading a resultSet after hasNext has returned false

Let me see if i cam gather the full stack trace at work today and get more info... thanks guys i will follow up shortly.
