AssertionError exception on a hibernate query in test only with version 3.17.7 and hibernate 6.6.*

[guillaumebesse]

Describe the bug

Before starting the web app, I populate several domain objects using Panache.

The exception is thrown only during tests when executing the following query:
find("from ...").list()

This issue appears with Hibernate 6.6, introduced in Quarkus 3.14.
If I downgrade the app to version 3.13.3, the exception no longer occurs.

My problem closely resembles the one described in this issue.
However, using the latest version of Hibernate does not resolve it.

I also tried Quarkus 3.18.RC1, but without success.

Extracting the code to reproduce the issue will be challenging, but I can try if needed.
I’m looking for ideas—why does this exception occur only during tests?
