Oleksii Miroshnyk ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5a157d9... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYjQ1NzBkMDdk... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16581?atlOrigin=eyJpIjoiYjQ1Nz... ) HHH-16581 ( https://hibernate.atlassian.net/browse/HHH-16581?atlOrigin=eyJpIjoiYjQ1Nz... ) in 6.2 I start getting Multiple '@FilterDef' annotations define a filter named error on startup ( https://hibernate.atlassian.net/browse/HHH-16581?atlOrigin=eyJpIjoiYjQ1Nz... ) Issue Type: Bug Assignee: Unassigned Created: 10/May/2023 08:38 AM Environment: Seems there is a change that breaks backward compatibility... I have some entity classes preprocessing that dynamically adds filter defs annotation based on some conditions So it can happen that entity A will have filterDefs filterA and FilterB and entity B will have filterDef filterA It was working in hibernate version 3-5 and in 6.1.7 in 6.2.2 it gives me an error. Can you please revert that condition or outline a context for filterDefs is it class(seems not), package, persistent unit ? I have 4 persistent units.. and a single instance of class transformer that intercepts class loading and it doesn't know anything about persistent unit that class belongs :( And maybe update docs as I didn't find any information about this requirement and some motivation of why it was added Priority: Major Reporter: Oleksii Miroshnyk ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5a157d9... ) ( https://hibernate.atlassian.net/browse/HHH-16581#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16581#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
