Re: [cdi-dev] @PostConstruct and @Inject methods in superclasses
Oki found it there:
most general superclass first.
of course the
interceptors_spec_1_1 only defines this for 'Lifycycle interceptors'
But what about my example 4, the shared @Inject method + @PostConstruct case?
Do we need to invoke all superclass injection first? thus do all @Inject fields + @Inject
methods + @PostConstruct first, then the one from the Horse class?
Could we also specify that all @Inject methods needs to get called before @PostConstruct?
txs and LieGrue,

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.
