Hello list, We're continually running into issues regarding Resteasy's lack of support for asynchronous requests through the JAX-RS client layer. This seems to be a feature of 2.0 that got implemented by essentially faking it with synchronous requests. I wonder whether Resteasy can truly claim to be a 2.0 compatible implementation given this serious caveat. There's a long-open PR: https://github.com/resteasy/Resteasy/pull/540 but it's been stuck since 2014 (!) with little movement. by this point there's now a competing approach that might upgrade the existing Apache HTTPClient to 5.0 (nearing release) which accomplishes similar goals without changing the underlying vendor, and might be easier for the project overall even if it means this AsyncHttpClient work doesn't get shipped. What's the status of this? Is this on any roadmap to be implemented any time soon? I'm surprised it lasted unimplemented this long, this seems like a critical feature to me, it's part of the spec! We'd consider contributing a HTTPClient 5.0 PR if that's what is needed to move forward, but the current situation is untenable for us and if this doesn't get fixed soon we will likely look for another product that can fulfill our needs. Thanks for any update you can provide, Steven _______________________________________________ resteasy mailing list resteasy(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/resteasy
