Knut Anders Hatlen commented on DERBY-3115:
-------------------------------------------

Connection.close() doesn't fail if auto-commit is true. I think it is reasonable to expect that the transaction is auto-committed on Connection.close() if the call doesn't fail. (Although it might be even more reasonable that the call fails.)

>             Project: Derby
>          Issue Type: Bug
>          Components: JDBC

> With autocommit, if an application neglects to close the result set
> and/or the statement, the closing of the connection will lose any
> updates performed via an updatable result set.
> If autocommit is false, SQL state 25000 invalid transaction state will
> be thrown, however.
> The JDBC standard requires that statements be closed when the
> connection is closed, cf.  JDBC 4, section 9.4.4: "All Statement
> objects created from a given Connection object will be closed when the
> close method for the object is called."  For updatable result sets,
> closing the statement would lead to a closing of the result set, and
> hence a commit of the updates.
> For the network client it works as expected.
