    if you can revert the changes to the imports it's good to merge IMO.
    
    you don't have to create a new PR. you can squash the commits if you wish, 
otherwise I'll do it when merging.

> Hello,
> In method open in JDBCInputFormat.java, while using dbConn.createStatement, 
> the resultSetType & resultSetConcurrency are hardcoded. 
> These two fields may vary with different JDBC drivers & hence it fails in a 
> few cases like SAP HANA Jdbc driver. 
> There are two variants of the method dbCon.createStatement, one with 
> parameters & the other without  parameters. Both should be supported. 
> Thanks & regards,
> Subhobrata
