[cdi-dev] CDI history question: non-void observer methods

[Ladislav Thon <lthon@xxxxxxxxxx>]

Hi,

me and Matěj and Martin were discussing observer methods earlier today and found, to my surprise, that the CDI specification in fact doesn't require them to declare a return type of `void` (even though all the examples in the spec, as well as all observers I've seen in practice, _are_ `void`).

Does anyone remember why that is? Is it an omission, or was that a conscious decision to allow people to call observer methods manually?

You can also vote for (or against) https://github.com/jakartaee/cdi/issues/636 if you think this is something we should (or shouldn't) rectify.

Thanks,

LT
