In the following application (called SystemConsole), the pack() call blocks
until the second thread terminates. Since the second thread shouldn't be
interfering with the event dispatch thread, I don't understand why AWT stops
at this point. (The second thread does run properly.)


import java.awt.*;
import java.io.*;

public class SystemConsole extends Frame {
    private TextArea text;

    public SystemConsole() {
super("System Console");
System.err.println("supered");
text = new TextArea(24, 80);
System.err.println("created");
add("Center", text);
System.err.println("added");
// Application blocks inside of pack() until ReadStdin terminates.
pack();
System.err.println("packed");
show();
    }

    public boolean handleEvent(Event evt) {
System.err.println("frame event " + evt);
if (evt.id == Event.WINDOW_DESTROY) {
System.exit(0);
return true;
}
return false;
    }

    public static void main(String argv[]) {
Thread t = new Thread(new ReadStdin());
t.start();
System.err.println("new thread started");
Frame f = new SystemConsole();
System.err.println("console created");
//t.stop();
//System.err.println("new thread stopped");
    }
}

class ReadStdin implements Runnable {
    public void run() {
System.out.println("test system console");
DataInputStream in = new DataInputStream(System.in);
String line;
try {
while ((line = in.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
System.out.println("IOException: " + e);
}
System.out.println("test done");
    }
}
