> If a table does not at the time of DROP, Netezza throws an exception but also
> sets the transaction as ignored (all changes through the connection will be
> ignored until the txn is either rollback or committed. While adding more
> tests, I missed the rollback and the create table was ignored, and
> subsequently ClassWriter.cleanColNames() threw NPE. I am fixing Netezza
> tests also, but we should check for this and throw a IOException instead of
> failing with NPE
