[cdi-dev] Duplicate javax.annotation packages and Java 9

[Mark Struberg]

Pulling this up again. 

It seems that the JDK team finally realised that they trashed tons of working projects with Jigsaw.
Of course, that's kind of natural with such a big change - but they have to clean it up now.

They are currently looking into removing all sorts of libraries from the JDK.
E.g. the whole JAX-WS and JAX-B parts.

Antoine, do you want to also contact them in regards of common-annotations?
Has anyone more information what is on the plate about what else is about to be removed from the JDK?

txs and LieGrue,
strub
