1.4 bug? or bad code? please I need help

Question

FTPClient.getFile(inputStream out,String filename) works fine if inputStream is directed to an output file. I added a Thread to read inputStream using piped i/o and works fine but the thread never ends. Seems like readLine() does not return null. Please I need help.
note: FTP package located finj.sourceforge.net
import java.io.*;
import org.finj.FTPClient;
public class FTPSimpleDemo extends Object {
public FTPSimpleDemo ( String server,
String user,
char[] password ) throws Exception {
PipedOutputStream pipeOut = null;
PipedInputStream pipeIn = null;
Thread reader = null;
FTPClient client =
new FTPClient(server,user,password);
//download file
try {
pipeOut = new PipedOutputStream();
pipeIn = new PipedInputStream(pipeOut);
reader = new PipeIn(pipeIn);
reader.start();
client.getFile(pipeOut, "J_Event.txt");
while(reader.isAlive() ||
!reader.isInterrupted));
pipeOut.close();
pipeIn.close();
client.close();
}catch(IOException e){e.getMessage();}
finally {reader=null;}
public static void main ( String[] args ) throws Exception {
new FTPSimpleDemo(args[0], args[1],
args[2].toCharArray());}
class PipeIn extends Thread {
private InputStream in;
private String str;
public PipeIn(InputStream in) {this.in = in;}
public void run() {
try {
BufferedReader br = new BufferedReader(
new InputStreamReader(in));
while ((str=br.readLine()) != null)
System.out.println(str);
br.close();
}catch (IOException e) {
System.err.println(e.getMessage());}
}

Heres a tip: forget that open source library unless you need to customize it or something. Use the ftp library that comes wih the JDK. It is in an unsupported package (sun.net.ftp) check it out it couldn't be simpler:
//you need this import statement
import sun.net.ftp.*;
//here is example code
String server = "ftp.fileplanet.com";
String user = "me";
String passwd = "1234";
FtpClient client = new FtpClient();
client.openServer(server);
client.login(user, passwd);
client.binary();
client.cd("games");
//DO NOT CLOSE THIS INPUTSTREAM UNTIL YOU WANT TO CLOSE YOUR CONNECTION
TelnetInputStream in = client.get("pacman.exe");
//now do whatever u want with this inputstream
byte[] bytes = new byte[4096];
int x = 0;
while((x = in.read(bytes)) != -1)
  out.write(bytes, 0, x);
  _totalBytes += x;
out.flush();
out.close();Also another tip for you to write code in the forum put your code between the [ code ] [ code ] tags
