Hi cpob,
Thanks for your help.
Using your xml in my (process-runner) program, I get the following log
(truncated for page's sanity)

The program's main part is as simple as that
| ...
| while(!instance.hasEnded()){
| System.out.println("*** signal ! ***");
| instance.signal();
| }
|
As you can see, I get the same order than previously.
nodeEnter > beforeSignal > nodeLeave > afterSignal
But I was wondering about some logs having exactly the same time, I did a
program that writes the running class name to a disk and to my surprise, the
launch order is still the odd looking one.
In my opinion, it would had been more intuitive to have something like
nodeEnter > (signal sent) > beforeSignal > afterSignal > nodeLeave
Although I don't get the use of the *Signal methods, should look deeper into
the documentation.
Thanks Cpob
