Few questions about Jetty Client:
1. Do it support SNI ? For example Apache Http Client do not  and we want to switch maybe to Jetty Client or some other.
2. Are there any plans to support JSR-339 ? I think it can be usefull to abstract implementation and be able to switch them. I found two implementations of this JSR - Jersey  (reference implementation) and Apache CXF . I'm not sure what the CXF project is but looks like it supports this JSR.
3. Do Jetty Client use NIO to do I/O or traditional blocking I/O API? E.g. Jersey uses thread pool and traditional I/O to do async requests (AFAIK) and this may not suit my needs.
