我调试到Net这个类的socketComminication（）这个函数的in.read(buffer, 0, 12);这一句的时候出了以上标题所写的错误！login（）函数与socketComminication（）函数的处理过程基本一致，为什么login（）这个函数没问题socketComminication（）这个函数却有问题？肯请大侠们帮我看看
一下是附的源代码
public class SocketPool {
private static int size = 10;

public SocketPool() {

if (infoArray == null) {

System.exit(-1);
return;
}

String hostname = new String(infoArray[0].getsServerAddr());
int port = infoArray[0].getnServerPort();

for(int count=0; count<10; ) {
try {
Socket socket = new Socket(hostname, port);
if(socket != null) {
count++;
socketPool.add(socket);
}
} catch (UnknownHostException e) {
continue;
} catch (IOException e) {
continue;
}
}
}

public synchronized Socket getSocket() {
//连接池为空，让线程等待
if (socketPool.isEmpty()) {
try {
wait();
} catch (InterruptedException e) {
}
}
return socketPool.remove(0);
}

public synchronized void closeSocket(Socket socket) {
socketPool.add(socket);
socket = null;
//连接为空，有加入一个socket时，通知其他线程有可用的线程
if (socketPool.size() == 1) {
notifyAll();
}
}
}

public class Net {
private static Logger log = Logger.getLogger(Jsds.JsdsName);

// 返回头
private int[] resHeader = new int[3];
// 返回参数
private byte[] resParams = null;

// 创建连接池
private static SocketPool pool = new SocketPool();

public int[] getResHeader() {
return resHeader;
}

public byte[] getResParams() {

* 取返回参数的给定长度字节

错误： in.read(buffer, 0, 12);
