Dear Adrian,

one last post about this topic, you are not expected to answer this. Perhaps it 
is resolved easier if we meet at a JBoss event (training etc.) some day.

I did ask you about a special patch made in 3.2.6RC2:

  | Sat Aug 28 11:42:08 2004 UTC (3 months, 3 weeks ago) by ejort
  | Branch: Branch_3_2
  | CVS Tags: JBoss_3_2_6_RC2, JBoss_3_2_7_RC1, JBoss_3_2_6
  | Changes since 1.20.2.7: +9 -3 lines
  | Diff to previous 1.20.2.7 , to branch point 1.20

  | Simulate the single thread per session to avoid concurrent delivery to a 
message listener, as required by the spec.

This is not one year old.

Yes, we did not pay you to answer our questions in this forum. But at least we 
did pay JBoss to get training and documentation. According to Marc Fleurys 
"Professional Open Source" this is the way it works. And it works so well that 
now also the (HTML) docs are free.

We have been considering that for some time. But your personal style is indeed 
not a motivating factor here.

We discovered this problem two weeks ago, but we were able to reproduce it only 
once since that time. If I were able to reproduce it consistently, i.e. if I 
run a test for say 2 hours, the problem appears at least once, then I could 
modify my setup (e.g. using JBoss 3.2.6) until the bug disappears. (Your 
statement about inserting Thread.sleep() made me curious whether there is some 
other way to trigger this bug. But I have no idea at the moment.)

As the empirical way did not show any success, I tried the analytical one 
looking at the Changelogs since 3.2.3 and at the source code.

The comment "Simulate the single thread per session to avoid concurrent 
delivery to a message listener, as required by the spec." did not sound like a 
bug fix in the first place, but most probably is one.

Therefore, I just asked for some background (motivation) for this very change 
in one source file.

If you answer would have been "cannot remember why I patched this," it would 
not have helped me, but it would have been OK.

So I continue to go through the source as I did in the forum thread

http://www.jboss.org/index.html?module=bb&op=viewtopic&t=45759

In this case I made some basic effort at least. BTW, do you use Doug Leas 
patched version now?

Perhaps we meet some day...

Regards, JÃrg
