Breaks Oracle system tests with issues like:

2026-07-28 20:22:36,742 - org.apache.pekko.persistence.jdbc.query.QueryTestSpec$TestActor -> ERROR[migrator-test-pekko.actor.default-dispatcher-8] [ migrator-test QueryTestSpec$TestActor - Failed to persist event type [org.apache.pekko.persistence.journal.Tagged] with sequence number [1] for persistenceId [my-1].

The ojdbc8 23.26.3.0.0 upgrade introduces a regression in the AutoKeyInfo metadata retrieval that breaks all Oracle tests using RETURNING clauses (auto-increment columns). At least, this is the best guess that Claude AI has. Oracle bug tracker is not public.

Apparently there is a post on the oracle forum about a regression affecting queries using quoted schema and table names. I can't go that forum post, but I could ask Google AI about it 🤷 : https://forums.oracle.com/ords/apexds/post/regression-in-23-26-3-0-0-when-using-quoted-schema-table-na-0722.
Probably just wait for the next version to show up.
