Jonas Gernot Steinke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) *commented* on HHH-16858 ( https://hibernate.atlassian.net/browse/HHH-16858?atlOrigin=eyJpIjoiYjkyZj... ) Re: Can't compare test expression of type [BasicSqmPathSource(type : Enum)] with element of type [basicType(a)5(java.lang.Integer,4)] ( https://hibernate.atlassian.net/browse/HHH-16858?atlOrigin=eyJpIjoiYjkyZj... ) I tested the changes by building hibernate from source (33a3ff2994d8412ef3c3d68ebe8af5574d05d597) and it still does not work. The error message has changed a little (which seems unrelated to the changes from https://github.com/hibernate/hibernate-orm/pull/6910 ) to: Cannot compare left expression of type 'java.lang.Enum' with right expression of type 'java.lang.Integer' Here the full stack trace: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name
