环境：应用服务器部署一个EJB应用。客户端写一个多线程测试程序，现在启了10个线程，下面的结果是控制台输出的一个片断，各位看官能看出些什么来么?

我很纳闷，不知道是客户端的问题，还是应用服务器中EJB的问题，为什么不是以下这样的结果呢？
thread3>321 Done.
thread5>324 Done.
thread1>319 Done.
thread6>329 Done.
thread4>323 Done.
thread7>325 Done.
thread9>327 Done.
thread10>320 Done.
thread8>326 Done.
thread2>328 Done.
thread3>322 Done.
thread5>351 Done.
thread1>320 Done.
既然是多线程，结果应该是乱的吧...大家看图说话，想想问题在哪里！

当然是你的程序作了控制了，贴出程序给大家看看

应该用SYCONIZE，将RUN方法，加锁。
