Question about testing preview features

[-]

Hi Alayachev,
1. You can check for the pull requests in the respective repositories;
but sometimes the changes might be committed directly, and some don't
belong to any of these repositories.
    For instance, Sequenced Collections was never a part of any of
amber; it's just in Stuart Mark's fork of JDK.
2. Of course. To integrate changes into mainline, they need to go
through reviews in pull requests in JDK itself. See
https://github.com/openjdk/jdk/pulls
3. Everything integrated into main jdk repository are via pull
requests like I answered in the last question.

Also for building 3 repos: They may contain changes that are not
integrated into mainline JDK. Especially valhalla; it is still in
prototypes, and the inlined objects have been named primitive classes,
inlined classes, null-hostile classes, etc.

Finally, for building from source, it can offer you the most
up-to-date content and, if you have patches, allows you to test out
your patches.

P.S. You are sending the mail to the wrong lists, I believe. This is a
question about JDK development in general, so I will reply to jdk-dev
list.
