答复: create a fork under openjdk

[李三红(三红)]

Hi Alan,
Thanks for your reply.
Let me elaborate a little bit on this -
1. Our cloud workloads are running on the top of JDK11(hard to keep them at
the head version due to enormous upgrade cost).
2. Based on these real use-cases,  we want to do the startup-related
enhancements(neither exploration nor prototyping, just resolving the actual
requirements) on JDK11
- At this moment, we are considering AppCDS(+upstream backports),
pre-initialization, and more optimization, e.g., AOT, in the future if
better for facilitating startup.
3. We plan to start with JDK11, but I think we can contribute them(or some
of them) up to the master later.

Thanks!
Sanhong

Is this a collection of small improvements that you are looking to upstream?
Is there any reason not to work with a fork from the main line as it already
has a lot of startup improvements since JDK 11. The jdk-sandbox repo [1] and
existing mailing lists could be used in that case. Some of the JEPs in
recent releases have accumulated changes in the sandbox during their
development.

Or maybe you have a larger multi-year project in mind? OpenJDK has Projects
[2] for collaborative efforts. Projects will usually involve exploration and
prototyping. Is that the sort of thing you had in mind? 
It might be useful to expand a bit on what you have in mind as it is hard to
know if this is about upstreaming changes or an effort that will explore
many directions.
