解决异常：Parser has reached the entity expansion limit "64,000" set by the Application

异常：分析器已达到由应用程序设置的实体扩展限制"64,000"

用JDOM分析一个超大的xml文件，大概20M，估计有很多Elements：

  SAXBuilder saxbuilder = null;
  Document doc_all=null;

  saxbuilder = new SAXBuilder(); // 新建立构造器
  
  try {
   FileInputStream xmlfile=new FileInputStream("verybig.xml");
   doc_all=saxbuilder.build(xmlfile); // 读入文件
  } catch (FileNotFoundException e) {
   System.err.println("缺少文件！请检查");
   System.exit(-1);
  } catch (JDOMException e) {
   System.err.println("解析XML模板文件出错！请检查");
   e.printStackTrace();
  } catch (IOException e) {
   e.printStackTrace();
  }

抛出异常：
reached the entity expansion limit "64,000" set by the Application.

中文翻译是：分析器已达到由应用程序设置的实体扩展限制"64,000"

原来是JAXP的bug，换JDK1.5解决！
