帮忙看一下java网络编程死锁的情况！

这部分的代码
URL path = new URL(gd.url);
String content = "";
HttpURLConnection connection = (HttpURLConnection) path.openConnection();
connection.connect();
InputStream urlStream = connection.getInputStream();
InputStreamReader isr;
if (gd.url.contains("suning") || gd.url.contains("amazon")) {
isr = new InputStreamReader(urlStream, "UTF-8");
} else {
isr = new InputStreamReader(urlStream, "GBK");
}
char[] buf = new char[2048];
int n = 0;
while ((n = isr.read(buf, 0, 2048)) != -1) {
// System.out.println(new String(buf,0,n).toString());
content += new String(buf, 0, n);
}
是什么原因呢 --------------------编程问答-------------------- 没看出来，何以断定是死锁了？
全都停在：

应该是在等待对方的数据而已吧。 --------------------编程问答-------------------- 没看懂~~ 帮顶 --------------------编程问答--------------------

locked <0x0000000090902dc0> (a sun.net.www.http.ChunkedInputStream)
有几个locked啊 而且一直动不了 --------------------编程问答-------------------- 代码还需要贴全一点吧，特别是加锁的部分
仅上上面的部分，多线程调用你这个方法是不会有问题的，因为每次都产生一个新的连接
补充：Java , Java SE
