[Please, give an email address for bug reports (or have I just
missed it?). Bug reports by web forms is just silly handholding
(supply a bug report template instead).]

JDK 1.1.2 (and 1.1.1) crashes when running the test program
below, when displaying output on a X11R6.3 server (on a
Sun IPX running NetBSD, but that shouldn't matter). It works
with 1.0.2. The X server is a vanilla installation of the latest
(last) version from the X consortium, i.e., R6.3, public-patch-1.


Test program:

import java.awt.Frame;
import java.awt.Label;

public class Foo extends Frame {

  Foo() {
    super("Foo");
    add("Center", new Label("Hello world!"));
    pack();
    show();
  }

  public static void main(String args[]) {
    Foo win = new Foo();
  }
  
}


Output when running on a Sun Ultra running SunOS 5.5.1:
