 原因是Swing的版本不匹配，一台机器是JDK1.7.0-b147（Swing版本为1.7），另一台机器是1.6.0_25-b06(Swing版本为1.6)

 JavaDoc中有对AbstractDocument,DefaultStyledDocument和PlainDocument，有以下说明：

From the Javadoc for AbstractDocument, DefaultStyledDocument, and PlainDocument:

'Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.'

 

 但是使用XMLEncoder/XMLDecoder后仍然有问题（或者用的不对），这里不详细表述;

 看来只能通过某种方式保证Swing版本一致（例如使用自带jre或者针对不同版本发布不同的程序包）。

下面是用来查看Swing版本的代码，来自于网络，具体出处懒得找了，这里不列出了：

 

import javax.swing.*; 
public class Version{ 
  public static void main(String args[]){ 
      JLabel l=new JLabel(); 
      Package p=Package.getPackage("javax.swing"); 
      if(p!=null){ 
          System.out.print("Swing Version: "); 
          System.out.println(p.getSpecificationVersion()); 

      } 
      p=Package.getPackage("java.awt"); 
      if(p!=null){ 
          System.out.print("AWT Version: "); 
          System.out.println(p.getSpecificationVersion()); 
      } 
     } 
   }
