PreDestroy on Extension class

[cjalmeida]

Seems like in Jboss 6.0.0.M4 a method annotated @PreDestroy in a Extension class (CDI portable extension) does not get called when undeploying/redeploying when packaged into an EAR.

Is that the correct behavior?

You are better off observing BeforeShutdown instead:

void beforeShutdown(@Observes BeforeShutdown event, BeanManager manager) { ... }

I don't that PreDestory is supposed to work on extensions, as they are not beans.

For each service provider, the container must provide a bean of scope @ApplicationScoped and qualifier @Default, sup-
porting injection of a reference to the service provider instance.

So the extension itself is not a bean, but rather for every extension a bean is created that allows you access to it.

Fair enough. The seam-scheduling module in sandbox contains such error - it tries to use PreDestroy to shutdown Quartz.
