Subject Planning for Java8 trunk
Date Fri, 13 Feb 2015 17:20:32 GMT
Hi All,

We've had a brief chat with Dan earlier about the possibility of 
introducing a Java 8 trunk after it was announced JAX-RS 2.1 API would 
be Java 8 based.

I'd like to justify here why IMHO this would be a very good thing for CXF:

- Java 8 is recognized to have a lot of new language features that can 
help with significantly enhancing the capabilities of a given project.
Functional programming, security related enhancements, etc, etc. IMHO
opening a Java 8 trunk would help us 're-invigorate' the CXF source (all 
frontends) with respect to the asynchronous, security-related and other 
processing and will likely lead to the introduction of the new features 
we can not even think of now. It will also excite the CXF community at 

- JAX-RS 2.1 requires Java8. JAX-RS 2.1 started its work in December 
2014 and I do expect Jersey and RestEasy teams publishing the snapshots 
more or less in sync with the ongoing API updates. Many users do want to 
play with the latest and greatest API asap. Besides, implementing 
iteratively would make it easier for us to deal with the other 
commitments we may have.

We have 3.1.0 and 3.0.x but there are no major differences between them 
from a feature point of view except that 3.1.0 is Java 7 based (with 
some related improvements).

So I believe it would be good to have a Java 8 trunk. The major question 
is when. But I hope it can be opened by the end of this year or possibly 
even a bit earlier.

IMHO the following may make sense:

Open it in the end of life for 2.7.x and either 3.1.0 or 3.1.1 releases.

2.7.x is nearly 2.7.15 now and I guess there will be 3 or so 2.7.x 
releases afterwards max.

If 2.7.x can be 'closed' and '3.1.0' released at the same time then IMHO 
it can just make sense to branch 3.1.x at that point and open a Java 8 
CXF 4.0 trunk. Otherwise do it after 2.7.x is closed and 3.1.1 is released.

Thoughts are welcome
Thanks, Sergey
