This sounds like a bug. I'd look for connections being continually opened without old ones being closed. My own personal style is that once I open a connection, I keep it open as long as possible, until I'm done using it, then explicitlyi close it.

Also, are you questioning the need to close these resources or the ordering?
I question that you should close a ResultSet when you are closing the corresponding Statement anyway. It just seems to make the code so much more complicated (especially if you try to get the exception handling right), without any benefit.

Ilja, Well yes. But if you have a JDBC framework to run queries this code is only written once. And it seems good to have on the off chance that you are using an old driver that doesn't give all the resources back.
