Subject Re: Remove obsolete RxJava code and keep RxJava2 only one
Date Thu, 16 Nov 2017 11:53:41 GMT
As I said, as far as CXF is concerned, there's no prospect of RxJava 
related code growing, and contributing to a CXF module noise to support 
a legacy library (I know I have to be careful now about the wording:-), 
I'm meaning here RxJava2 embracing org.ractivestreams) is not worth it IMHO.

If you check my earlier reply, I suggested to keep it where it is now 
after all. So if we have some users somewhere deciding to stay with 
RxJava then they'd have the support they need.

Cheers, SErgey
