Do we need to support build 3.5.0 with JDK-17 ? For Jakarta ee9 support branch 4.x with source code change to support jakarta namespace , we have to wait for spring and other third party dependencies jakarta ee9 ready. Now we don't know when these dependencies are all ready and we can start this work. Given there is no features added in Jakarta ee 9.1 besides the namespace change, we can provide the jakarta calssfier maven artifacts and binary release in 3.6.x or 4.x with transformation or other better approach will be enough.We provide jakarta ee9 support early, then we can get more feedback on this topic. > Option #2: > - release 3.5.0 in preparation to JDK-17 LTS, use JDK-11 as baseline > - handle javax by a build setup (with api validation at build time to > avoid regressions) and use jakarta package as main api in the project > (Romain), or > adding a new maven module to transform cxf artifacts with jakarta > package name (Jim) > > Option #3: > - release 3.5.0 in preparation to JDK-17 LTS, use JDK-11 as baseline > - move master to 4.x to continue the work on supporting Jakarta 9.0+, > with JDK-11 as the minimal > required JDK version (Jetty 11, ...) > > Thank you! > > Best Regards, > Andriy Redko > > > JM> On Wed, Aug 11, 2021 at 10:05 AM Andriy Redko <drr...@gmail.com> > wrote: > > >> Hey guys, > > >> I would like to initiate (or better to say, resume) the discussion > >> regarding CXF 3.5.x and beyond. > >> The 3.5.x has been in the making for quite a while but has not seen any > >> releases yet.
