Try this solution at your end. It worked for me. Close the connection in try/catch block and just after closing the connection, write-

Thread.sleep(1000);

In this case you can write it as-

finally {
            try {
                if (conn != null && !conn.isClosed())
                    {
                    conn.close();
                    Thread.sleep(1000);
                     }
                }
            catch (SQLException e) {
                e.printStackTrace();}
}
