>    Affects Versions: 1.6.0
>            Reporter: Gardella Juan Pablo
>            Priority: Major
> Discovered during NIFI-5049. According [ResultSet.next() 
> javadoc|https://docs.oracle.com/javase/8/docs/api/java/sql/ResultSet.html#next%E2%80%93]:
> _When a call to the {{next}} method returns {{false}}, the cursor is 
> positioned after the last row. Any invocation of a {{ResultSet}} method which 
> requires a current row will result in a {{SQLException}} being thrown. If the 
> result set type is {{TYPE_FORWARD_ONLY}}, it is vendor specified whether 
> their JDBC driver implementation will return {{false}} or throw an 
> {{SQLException}} on a subsequent call to {{next}}._
> With Phoenix Database and QueryDatabaseTable the exception 
> {{java.sql.SQLException: ERROR 1101 (XCL01): ResultSet is closed}} is raised.
