Review Comment:
I believe this was the plan all-along (wait for Hadoop 3.5 upgrade then bump
to whatever latest JDK version this supports). Since Hadoop 3.5
[supports](https://hadoop.apache.org/docs/r3.5.0/) JDK 21 client-side and it is
the only thing preventing us from upgrading the compiler version, it seemed
correct to do. Whether we wait for JDK 25+ support in Hadoop before decoupling
it from critical extensions (e.g. Parquet) is IMO a separate issue, and we can
in the meantime upgrade the compiler version. Let me know if you have any
hesitations.
