Thread.stop/join problem on kaffe-0.9.2

[Yuji Nimura]

Hi,

I found the following program does not work fine with kaffe-0.9.2 on
HP-UX 10.20.
It seem that kaffe-0.9.2 has a problem on Thread.stop/join mechanism.
How about kaffes on the other platforms ?

================ the prgoram: tthrd1.java ================
class btst1 extends Thread
{

  public void run()
    {
      System.out.println(isAlive()+" 1");
      this.stop();
    }
}

public class tthrd1
{
  public static void main(String args[])
    {
      btst1 b=null;
      int c = 0;
        
      System.err.println("main start");
      b = new btst1();
      b.start();
      System.err.println("thrd start");

      System.err.println("thrd join");
      try{b.join();}catch(InterruptedException e){}
      System.err.println("main end");
    }
}
==========================================================
================ outout of kaffe   =======================
myhost: kaffe tthrd1
main start
thrd start
thrd join
true 1
(kaffe stops and never prints "main end")
================ outout of another java VM ===============
myhost: java tthrd1
main start
thrd start
thrd join
true 1
main end
myhost: 
==========================================================

I try to debug this problem but I can not fix it.
The following is the stack trace list from core when the kaffe stops. 
I made a special version of kaffe which use default signal handers and
I sent SIGSEGV to the kaffe to get the core.
