Stream closed while copying?

Question

Hi, i am trying to open a connection to a url and then trying to save the page to a location. i frequently face a problem in which the copying terminated by itself. This only happens when i try to copy a webpage with big file size. However sometimes it manage to succesfully copy the files. So, can anyone tell me what wrong? Sometimes it can, sometimes cannot. I put my codes in a try catch block but nothing was done in the catch block although i try to print out the error message. My partial codes shown below.
URL _url = new URL("http://www.google.com");
OutputStream out = new FileOutputStream("test.html");
URLConnection conn = _url.openConnection();
conn.connect();
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((inputString = reader.read()) != -1) {
    out.write(inputString);
out.flush();
out.close();Thank you.

i managed to track down the error stack. i think the code dies during the execution of method available() of java.net.PlainSocketImpl. I think this is the socket connection problem which throw the exception. the socket should be instantiaed when i call url.openConnection() if i not wrong. and why it dies i really clueless. and somemore it does not die at all times. most time it is ok. any help is very appreciated. below is the error msg. thanks.
