> getTransactionIsolation() is implemented by means of
> rs = getTransactionIsolationStmt.executeQuery("values current isolation");
> This will activate a transaction. Thus the code snippet
> Connection conn =
> DriverManager.getConnection(url);
> conn.setAutoCommit(false);
> int tx = conn.getTransactionIsolation();
> conn.close();
> will fail with
> java.sql.SQLException: Cannot close a connection while a transaction is still active.
