In general no good idea to follow up own mails, but
for your imagination what kind of bugs I am speaking about
look at this:

public class Moo 
{
 public static void main(String args[])
 { 
      try
      {
	  int M=0,o=0;
	  o=o/M;
      } 
      catch (Exception eeee)
      {
         System.out.println("catch ex "+eeee);
      }
      try 
      {
	 Thread.currentThread().sleep( 1 );
      } 
      catch (InterruptedException e)
      {
	 System.out.println("main sleep interrupted");
      }
      System.out.println("END");
 }
}


Moo running jdk1.2v1a+TYA1.3/unreleased (***) gives this:

                  green  native
	         ======  ======
TYA compiled		 
EXC_BY_SIGNALS:   hangs   okay
NO EXC_BY_S...:   okay    okay
-------------------------------
sunwjit       :   hangs   okay

Does a such TYA release really makes sense..?
Consider: most users would use EXC_BY_SIGNALS and green threads
as best choice. And in general it's much slower than jdk1.1+TYA.

Still interested in release ?????? 

Cheers,
Albrecht
PS: 
(***) Moo running -green using sunwjit hangs too, of course.
