Marko Bekhta ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HV-1937 ( https://hibernate.atlassian.net/browse/HV-1937?atlOrigin=eyJpIjoiYjBkNGYx... ) Re: Failed to validate items in an attribute of type Collection of Java Record ( https://hibernate.atlassian.net/browse/HV-1937?atlOrigin=eyJpIjoiYjBkNGYx... ) Thanks for providing the additional information. If it works fine with a simple maven build, then the problem isn’t coming from the validator but rather from the IDE. I’ll try to reproduce it with what you’ve provided additionally, but if the problem is not reproducible - I’m afraid there’s not that much we’d be able to help with.
