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！
