Re: [weld-dev] PostConstruct & PreDestroy in Java SE

And before there are any questions: it's not directly stated inside the CDI spec but in the TCK documentation: http://docs.jboss.org/cdi/tck/reference/1.0.4.SP1/pdf/jsr299-tck-referenc... "JSR-330 - CDI builds on JSR-330, and as such JSR-299 implementations must additionally pass the JSR-330 TCK." again: I agree with Martin that you should better not use it. But it should work nontheless.
