Oracle JDBC 没响应，是不是BUG？

Question

在Java 中执行下面SQL语句没有响应，DEBUG 无法跟踪代码，但此语句在SQL DEVELOPER 执行没问题，在Java代码中执行其他 SQL 语句基本也没问题。

[code="sql"]insert into T1 (ID, VALUE) select ID, VALUE from T2[/code]

[code="java"]import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

import oracle.jdbc.driver.OracleDriver;

public class TestOracleUtil {

public static void main(String[] args) throws SQLException {
    String sql = "insert into T1 (ID, VALUE) select ID, VALUE from T2";
    update(getConnection(), sql);
}

public static Connection getConnection() {
    new OracleDriver();
    String serverName = "192.168.1.3";
    String portNumber = "1521";
    String sid = "ORCL";
    String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":"
            + sid;
    String username = "test";
    String password = "test";
    try {
        Connection conn = DriverManager.getConnection(url, username,
                password);
        return conn;
    } catch (SQLException e) {
        e.printStackTrace();
        return null;
    }
}

static void update(Connection conn, String sql) throws SQLException{
    Statement smt = conn.createStatement();
    smt.executeUpdate(sql);
}

}[/code]

如果数据库连接没有报错的话，试试先关闭取消自动提交，[code="java"]conn.setAutoCommit(false) ; [/code]，在最后手动提交，[code="java"]conn.commit();[/code]
