Yes, imo the things which are not yet clear are the order between @Inject and
@PostConstruct, and wha happens if we have a class hierarchy.

Hi,
for @Inject there is an order specified in JSR 330. Imho we should specify that same order
for @Postconstruct if we have specification for it yet.

Arne

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 ;)
