Re: [cdi-dev] @PostConstruct and @Inject methods in superclasses
This is actually covered by the interceptors specification, from memory I am pretty sure
the base class method is mean't to be called first, but the spec gives you the full
order.
@Inject methods are called before @PostConstuct (the are called in InjectionTarget.inject,
which gets called before InjectionTarget.postConstruct).
I don't think we specify an order for @Inject methods.

Hi!
JSR-250 common annotations is pretty thin about having @PostConstruct in multiple class
hierarchies. It just says that there must only be one single method annotated with
@PostConstruct in a class. Thus my question:
If I have
public class Animal {
@PostConstruct
public void doInit() {..}
..
}
and
public class Horse extends Animal {
@PostConstruct
public void doSomeOtherInit() {..}
..
}
1.) for a contextual instance of Horse, will Animal#doInit() get executed or only the one
from the 'effective' class?
2.) if 1.) was yes, then In which order do they get executed? Is this specced somewhere?
3.) Same scenario with @Inject methods. Do we specify an order?
4.) Both classes have @Inject methods and @PostConstruct. Again: which order of
invocaition?
Just that you understand my intention: we had a @PostConstruct method in Horse which did
set a 'cached' flag in Animal. Turned out that this was a random generator
depending on the intsalled server ;)
