邂逅JVM中的Bug

作者：张桂权

接触JAVA已有两年多的时间了，应该说对她已经有了一个很深刻的了解，可还是第一次邂逅JAVA虚拟机的bug，而且更然人吃惊的是代码竟然只有那么可怜的几行。

这一天我用的IDE是IBM的开源软件日食（eclipse 3.1）版本，其他的都是SUN的底层软件包了。JDK 1.5版,J2SDK 1.5版。不过在我的电脑上还装了JCreator Pro 1.5 版，还有J2EE,J2ME,Java Card等，不过我看了一下这与bug没有什么关系。主要是内存出现了错误。代码还没有写完，就崩溃了，真是很遗憾的。我把这个问题告于大家，让大伙也看看究竟怎么一回事！没准你也会碰上她呢。祝你好运！

程序代码如下：

import java.awt.*;
import java.awt.Event;
import javax.swing.*;

public class jiecheng extends JFrame {

private JPanel contentPane = new JPanel();
private JLabel prempt = new JLabel();
private JTextField input = new JTextField();
private JLabel prempt2 = new JLabel();
private JTextField output = new JTextField();
private JButton submit = new JButton();
private JButton reset = new JButton();
private String temp = new String();

public jiecheng(){

contentPane = (JPanel)getContentPane();
setSize(350,200);
setLocation(300,400);
setVisible(true);
setResizeable(false);
prempt.setText("请输入一个非负整数");
prempt.setBounds(12,20,135,12);
contentPane.add(prempt);
input.setBounds(140,12,200,24);
contentPane.add(input);
prempt2.setText("最后的阶乘为");
prempt2.setBounds(12,60,135,12);
contentPane.add(prempt2);
output.setBounds(140,48,200,24);
contentPane.add(output);
submit.setText("确定");
submit.setBounds(60,120,60,24);
contentPane.add(submit);
reset.setText("重置");
reset.setBounds(150,120,60,24);
contentPane.add(reset);

．．．

}

public static void main(String[] args){

jiecheng jc = new jiecheng();

}
}

错误报告内容如下：

除5、6之外的几个文件似乎是一个内容的不同版本罢了，可能是多次编译产生的，因为只有几个参数不同而已。

主要因为我在“构制函数“中初始化的变量多了点让系统内存分配产生“溢出”造成的。还有一点当时我还安装了一个@Home的一个客户端（为科研做点贡献罢了），所以绝大部分的内存都被占用了。所以才很＂荣幸＂的邂逅了JAVA虚拟机的漏洞！
