Hi, I’m encountering a race condition during application startup involving: custom PhysicalNamingStrategy JDBC metadata access via JdbcEnvironment HikariCP connection initialization Context Spring Boot Hibernate ORM HikariCP 3.5.6 6.2.9 default pool via Spring Boot Problem Our custo…

I guess you debugged or looked into the code already. Do you have a hint where this might go wrong?

Hi @beikov , thanks for your comment. Yes, I looked into the code, and based on the description of JdbcEnvironment.getCurrentSchema(), this is expected behavior. If JdbcEnvironmentInitiator fails to access the JDBC metadata during initialization, it will fall back to default values, including hibern…

I’m having a hard time understanding what is happening. You can configure hibernate.boot.allow_jdbc_metadata_access=require to make sure that the app fails if the JDBC metadata is not accessible. What I don’t understand is where the concurrency problem should be. If HikariCP hands out a connection …

Let me try to clarify the scenario more concretely. I’m observing inconsistent behavior during application startup where a custom naming strategy depends on the connection’s schema name, which is not always accessible at the time table names are resolved. Case 1 (expected) - 99% Hibernate initia…

Like I already wrote, you can configure hibernate.boot.allow_jdbc_metadata_access=require to make sure that the app fails at startup if the JDBC metadata is not accessible. Why the metadata is not accessible is still not clear to me, but that’s not a Hibernate ORM issue.
