> JDBCInputFormat.nextRecord(..) has misleading message on NPE

> Key: FLINK-3472

> Project: Flink
> Issue Type: Bug
> Affects Versions: 0.10.2
> Reporter: Ken Geis
> Assignee: Chesnay Schepler
> Priority: Minor
>
> JDBCInputFormat.nextRecord(..) assumes that a NullPointerException could only
> occur by the resultSet being null. It rethrows an exception with the message
> "Couldn't access resultSet". See FLINK-3471 for an example of where the NPE
> could come from another situation. Either the message should be changed or
> the scope of the try/catch should be tightened around the
> {{resultSet.next();}}
