Bean's destroy method not invoked when kernel is shut down [message #749397]

Hello everyone.

I am creating a Spring bean declaratively with a "destroy-method" attribute defined in it. When I shut the Virgo kernel down (using the standard script), however, this method is not invoked. Why is that? What do I have to do?

I have also tried to register an ApplicationListener for ApplicationContextEvents, listening for ContextStoppedEvents specifically, but the call back method is never invoked either when the server is shut down.

TIA,
B.

I don't know if this helps, but we use an ApplicationListener which is, we assume, driven during shutdown. You might like to verify this using a "suspend VM" breakpoint. See here in OpenGrok.

Hi Glyn.

As my second sentence in my original message states, I have tried that route too and my breakpoint in the callback method is never exercised.

Hi Glyn. No cigar, I'm afraid.

I just tried implementing the same kind of listener as in your example (I was originally listening for type ContextStoppedEvent explicitly), but the call back still does not get invoked.

Any alternative you can think of?

What I simply want to do when Virgo is shutting down is remove bundles from the pickup directory that I deposited there earlier.

Thanks,
B.

Sorry for the late reply - I forgot to subscribe to the thread (shame respondents aren't automatically subscribed, isn't it?).

One brute force way is to detect shutdown using a synchronous bundle listener as here.

Fantastic, Glyn, thanks!

Seems like a rather last ditch way to do it, but if all else fails...

Doesn't it seem like a bug to you though? Surely if the container is shut down, the declared destroy method of all instantiated beans should be invoked. Do you agree?

The other (probably silly) issue I face is that, despite my attempts to delete the plan file from the pickup directory (in other cases too, not just when I shut down), the delete operation fails presumably because the file is locked by the running Virgo related process. Any work around that one?

Thanks again,
B.

Could be a bug, but we'd need to spend some time analysing the behaviour to see what is feasible given the various components involved. Would you care to raise a bug and attach a trivial example which reproduces the problem?

Will create an example and raise a bug in a couple of days, thanks.

What about the other issue (admittedly not strictly on topic, but as long as I have your ear, Glyn... Twisted Evil

)
