No, if you run in the auto-commit mode - JDBC specification requires us to
close all open result sets before executing the next statement. This was
changed in JB 2.0 together with dropping the result set caching in
auto-commit mode.

You have to switch the auto-commit mode off to get your previous behavior
back. Alternatively we can think about the compatibility mode that would use
result set caching in auto-commit mode and ignore the JDBC specification if
more people have problems with this behavior.
