java.lang.AbstractMethodError: Receiver class does not define or inherit an implementation of the resolved method 'abstract boolean isClosed()' of interface java.sql.ResultSet.

Hello!

I was trying to use sqlline with an older system/driver and encountered the below error:

It seems like this happens if the driver was built with an older version of java (different driver, same issue):

Can you give more details:

• What JDK was the driver built on?
• What JDK are you running on?
• When was the isClosed() method introduced?

i saw your proposed fix #482 but I don't think that catching errors is a good idea. If a driver doesn't have the required methods to run on a particular JDK I don't think that sqlline should be trying to apply duck tape.
