Re: [Wrapper-user] Shutdown hook not triggered when jvm is unexpectedly killed

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

Nick,
    Calling System.exit() is considered as a normal shutdown request by 
the Wrapper.
It will cause the Wrapper to shutdown normally.   If on the other hand, 
you call
Runtime.getRuntime().halt() the Wrapper will interpret is as the JVM 
crashing and it
will be restarted.  This is because the exit() causes shutdown hooks to 
run whereas
halt() does not.

    You can add some control over what happens when the JVM exits by 
setting up
Event handlers based on the JVM exit code.  See the following for details:
http://wrapper.tanukisoftware.org/doc/english/prop-on-exit-n.html

Cheers,
Leif
