The Wrapper should be following the same rules as the regular Java 
executable
when run without the Wrapper.   The Wrapper has to do its own thread 
counting
because it starts its own non-daemon thread.  If the Wrapper did not do any
special counting of the threads, then the JVM would never shutdown.  By 
waiting
until there is only one non-daemon thread running, the Wrapper is able 
to work
around this.

What happens when you run your application without the Wrapper or its helper
classes.  If you truly do not have any non-daemon threads running then Java
should assume that your application is stopped and exit.  That is the 
difference
between daemon and non-daemon threads.

What JVM are you running?  This may be an issue with a JVM I have not seen
before?

I will need more info to tell you the problem without guessing.
Could you enable debug output and then post the wrapper.log file that
contains both the startup and shutdown of a single run of your
application.  Delete any existing log file first so you don't send the log
of multiple invocations.

Cheers,
Leif

P.S. There is no need to cc the wrapper-cvs list as that just gets me 2 
copies of your mail. :-)
