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

[<nic...@uk...>]

I would have thought that this is expected behaviour.
Killing a process from the Task Manager is akin to a kill -9 on unix. Its
not a graceful shutdown by any means. So I wouldnt expect your shutdown
hook to get called.

In this situation, I would expect the wrapper to restart it though....

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


Hello,



I am using integration method 1 to wrap an in house developed java
server app with the Java Service Wrapper 3.1.2. On both my development
server Win 2k3 and my PC Win XP SP2, when I kill (via Task Manager) the
JVM that is monitored by the Wrapper, my shutdown hook does NOT get
executed. Not that I like to go around killing java processes, but this
app's JVM has been disappearing on its own on our production servers,
and I was hoping to employ both the Wrapper and some extra logging in my
shutdown hook thread to help figure out why. My hook DOES get executed
when I shut the wrapper down normally and when I kill the wrapper
process and let the JVM die from lack of wrapper pings. My question to
anyone kind enough to read this is: is this normal expected behavior and
if so why?



Thanks in advance,



P.S.

This product is very cool; sure beats what we have used in the past to
run java apps as Windows Services.
