Richard Turner ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5bed604... ) *commented* on HHH-16351 ( https://hibernate.atlassian.net/browse/HHH-16351?atlOrigin=eyJpIjoiNTRhMm... ) Re: Migrating from 5.6 to 6.1 to_timestamp(double) function now throws QueryException ( https://hibernate.atlassian.net/browse/HHH-16351?atlOrigin=eyJpIjoiNTRhMm... ) Thanks for the update, I also see this error during startup now: HHH000099: an assertion failure occurred (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: value involves formulas Which is thrown when evaluating an entity with a @Formula annotation like this: @Formula("(select ra.VALUE from PUBLIC.REALM_ATTRIBUTE ra where ra.REALM_ID = ID and ra.name = 'displayName')") But the calculated field seems to function OK, is this the same issue of stricter validation?
