[jcflack]

Does your build succeed using the branch in PR #451 ?

If so, the PL/Java release once PG 16 comes out should be ok.

[fmbiete]

Yes, it succeeds against that branch with PostgreSQL 16.0 GA

[jcflack]

I confirmed that a couple days ago and merged that branch.

I rarely recall such a close span between a PG release and a Java release; Java 21 is GA tomorrow, so I think I'll wait for that and confirm there's no funny business, then do a release.

[jcflack]

Believed resolved in 1.6.6.
