> Here is related code:
> {code}
>     Connection conn = null;
>     boolean committed = false;
>     try {
>       conn = getConnection();
> ...
>     } finally {
>       if (!committed) conn.rollback();
>       conn.close();
>     }
> {code}
> If getConnection() throws exception, conn.rollback() would be called - leading to NPE.
