Here's more information about each backport:

Those required re-work:

Those were "clean" backports (for some definition of clean):

However I have a real problem marking clean backports as a "simple hg
import of the original changeset", because it's never the case. Each
patch needs to be studied and understood and tested, even when it
applied cleanly, so there's real work involved, and you can see this
for example in the discussion about JDK-8223697, which despite
applying cleanly was actually a result of a few back and forth and
required assessment of another patch that didn't apply cleanly. I
would be very worried if any developer would apply a patch, see that
it's clean and just pushes it.

There's maybe an issue in the process where the updates project is
also responsible to produce the topmost stable release (i.e. JDK15u)
and so the Committer role is akin to that of Committer for the jdk-dev
in this case, but for the most part the updates produce maintenance
releases of typically older trains, like JDK 11 or 13 (8u is not in
this by chance, because back then we had a separate update project for
each version).

Selecting a Committer for those versions would be very difficult if we
only allowed non clean backports as contributions, because the reality
is that most of the backports apply cleanly or with trivial
modifications, so the rationale behind a Yes vote, in my opinion,
should be the quality of the work this developer does (which means
also ensuring that a patch that is a clean backport is also
contextually accurate and does not have unwanted side effects), the
frequency of his contributions and the likelihood that he will
continue contributing. Of course, YMMV, and I respect that.

Jie didn't push those patches, he contributed them and someone
(usually Christopher!) pushed them.
