After 3.2.0 update, the querydsl embedded column type comparison operation is not possible.

[phjppo0918]

After 3.2.0 update, the querydsl embedded column type comparison operation is not possible.

In version 3.1.4, it worked without any problems, but the equals operation for embedded columns does not work properly after the 3.2.0 update.

Currently operating based on kotlin - JVM17.

The error code is as follows.

java.lang.IllegalArgumentException: org.hibernate.query.SemanticException: Cannot compare tuples of different lengths

This is almost certainly a Hibernate issue. Please try Spring Boot 3.1.x upgraded to Hibernate 6.3.2.Final to see if the problem occurs. You may also want to try Spring Boot 3.2.0 with Hibernate 6.4.0.Final to see if they've already fixed the problem (there is some similarity with HHH-17454).
