javamail 多线程取邮件 线程hung的问题

用多线程采用IMAP方式读取邮件服务器邮件,平时测试都没问题,各种连接异常啊超时异常啊也都好使,但是运行一天左右时间后,出现线程hung掉的情况,主要是在store.connect的语句那块,直接卡死线程无响应了,线程还在没有当掉,设了connect的timeout,但也不抛异常,也不阻塞,就这么一直Runnable着：线程3033就是那个无响应的.

我想了个办法,用FutureTask包装了下放到自定义的TimeOutThread线程里,线程执行超过10分钟还没结束,就cacel掉这个线程,然后外头再启动一个新线程进来.结果发现一但到了store.connect卡掉那块,旧线程是能cancel掉,但是新起来的线程一直处于timewating状态,都没有进入到run里,也不知道为什么,jconsole跟进去stack信息如下：
