Fetching multiple fields of the same base class with InheritanceType.SINGLE_TABLE throws PropertyAccessException

Hi Marco, thank you for the update!

I will look out for the new version release(s) and test.

Hi and . Another similar issue was recently fixed: .

Please let me know if the error persists for you after this change, you can wait for 6.2.8 or 6.3.0 to be released or test using the latest Hibernate snapshot.

Hello @Marco Belladelli, I am seeing this exact same error when using a InheritanceType.JOINED type on the parent. This was working fine on SpringBoot 3.0.6 (Hibernate 6.1.7.Final)

I am upgrading to SpringBoot 3.1.2, which uses Hibernate 6.2.6.Final. I’ve also tried forcing the 6.3.0.CR1 version and still see the error. This is written in Kotlin.

Note: I understand @DiscriminatorColumn is unnecessary for a Joined Inheritance, but this was existing logic I have yet to change.

Hello , since the fix for was integrated and released in version 6.3.0.CR1 it would be nice if you could test if your issue persists with Hibernate’s latest version.

Hello , thanks for reporting the issue. From what you’ve described, this seems closely related to , in that you’re trying to (left) join an association to a sub-type entity in an inheritance structure, and expect only the records corresponding to that sub-type to be joined.

To be sure of this, though, we would need to see the complete mapping of you model or, even better, you could provide a simplified reproducer using our test case templates.

Meanwhile, the issue I mentioned has a work in progress fix, you can follow that for any updates.
