写基于TCP/IP多线程的是抛出Socket连接异常

1、问题

public void run()

{

try {

while(isStart)

{

synchronized(this)

{

wait();

}

if(object!=null)

{

System.out.println(object.getType());

oos.writeObject(object);

oos.flush();

}

if(oos!=null)

oos.close();

//if(socket!=null)

//socket.close();

}

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

publci void run(){}方法中的写消息出现错误，抛出的错误是Socket closed。检查发现并没有关闭Socket连接，不知为何？
