Re: [Wrapper-user] How do I prevent wrapper from re-starting after exit ?

[Leif M. <le...@ta...>]

Elizabeth,
    Yes, as I thought, it appears that the shutdown hook is not being 
run when your
application calls System.exit.  I did a Google search and am not yet 
sure how this
could be happening as you are using java 1.4.2... :-/  From the logs, I 
can see that
the wrapper's shutdown hook is indeed being registered:
INFO   | jvm 1    | 2005/12/07 21:55:11 | Wrapper Manager: Registering 
shutdown hook

    Any idea on your end?  I have never seen this in any JVM other than 
old 1.2
versions.  I'll post back if I find anything.

    As a workaround, calling WrapperManager.stop() rather than System.exit()
will make sure the JVM exits correctly.

    The problem is that if the JVM exits without its shutdown hook being 
run, or if
the user code calls System.halt() then the Wrapper process will assume 
that the
JVM crashed.  This is why it is being restarted.

Cheers,
Leif
