connect() is typically called to get a connection and it will validate that 
there is a non-null Connection.  I have unit tests which leverage that 
constructor and run clean with that change.

I agree that commit(), rollback, etc  should call checkState() and that is 
another fix I need to do but the potential for the NPE is there depending on 
which constructor was used and if you did something silly like making a 
rollback without doing any work.

I can revert that change if you like but I have not seen any failures under 
what I would term normal use.

I am not sure I agree with the code either, just want to spend a bit more time 
looking at the code flow and see what tests if any we have here
