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.
