Step to reproduce, take for example existing
JdbcComplexQuerySelfTest
and change implementation with:

{noformat}
    @Override protected void beforeTest() throws Exception {
        Properties cfg = new Properties();

        cfg.setProperty(PROP_NODE_ID, grid(0).localNode().id().toString());

        stmt = DriverManager.getConnection(BASE_URL, cfg).createStatement();

        assert stmt != null;
        assert !stmt.isClosed();
    }
{noformat}
