在做javamail通过pop3解析邮件的时候，在解析邮件包含附件的时候，在测试服务器上出现了以下异常

但是这个在本机并没有这样的异常出现。网上查了不少帖子，真正能解决这个问题不多。

 

不过有个帖子给了我点提示

 

http://forums.sun.com/thread.jspa?forumID=43&threadID=5152319

 

后来部署到另外一台测试机器上发现能正常解析，于是停掉了原来测试机的杀毒软件，就能正常解析出来了

 

不过也在解析的时候首先判断了message是否继承与Part接口的

 

部分节选代码如下

		try {
			if (msg instanceof Part){
				Part part = (Part) msg;
	
				if (part.isMimeType("multipart/*")) {
					Multipart mp = (Multipart) part.getContent();
					System.out.println(mp);
					int count = mp.getCount();
	
					for (int i = 0; i < count; i++) {
						Part p = mp.getBodyPart(i);
						//某些处理
					}
	
					mp = null;
				}
			}
		} catch (MessagingException e) {
