1. Even the silliest standalone program (that uses the AWT) compiled
   with JDK 1.1.2 or 1.1.3 barfs when it is displayed on an NCD X
   terminal (but 1.0.2 works great, which is a bit odd).

2. Here is an example (F.java):

import java.awt.Frame ;
import java.awt.Button ;

public class F extends Frame {

  public static void main(String[] args) {
    new F() ;
  }

  F() {
    add("Center", new Button("HAR!")) ;
    resize(200,200) ;
    show() ;
  }
}

3. Here is what happens when this is run:

SIGSEGV 11* segmentation violation
    si_signo [11]: SIGSEGV 11* segmentation violation
    si_errno [0]: Error 0
    si_code [1]: SEGV_ACCERR [addr: 0x14]

stackbase=EFFFE810, stackpointer=EFFFD3F0

Pretty, isn't it?

4. N/A

5. It seems not to like something in Motif. And yet, we are
   using CDE 1.0.1 as shipped with Solaris.
