[cdi-dev] @PostConstruct on inherited class

[Martin Kouba]

Hi JJ,

I believe Y.init() should be invoked and only once. It works for me on AS7 and Weld 1.1.5. What container do you use?

See also Interceptors 1.1 spec, chapter "Multiple Callback Interceptor Methods for a Life Cycle Callback Event":
"If a lifecycle callback interceptor method is overridden by another method (regardless of whether that method is itself a lifecycle callback interceptor method (of the same or different type)), it will not be invoked."

By the way if X.init() wasn't overriden, it would be invoked first (see the same chapter in spec).
