Please see "Code Reviews" on the Group page
https://openjdk.org/groups/client-libs/ where it says
The Java Client Library Group has always standardized on two approvals -
where at least one must have the Reviewer role.
Historically this was addressed entirely by social conventions but today
the tooling plays a role - and the JDK project is set up to mark a PR as
ready for integration after a single approval by a person with the
Reviewer role - which is not consistent with the Client Libraries policy.
The tooling cannot automatically enforce this on a per-module basis and
it is not reasonable to expect others to add "/reviewers 2" to every PR.
The fixer therefore needs to understand the policies and wait for a
second approval.

As an example of a PR about which there was zero urgency and should have
had a 2nd approval see
