Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiODJiZTNlMzdl... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15551?atlOrigin=eyJpIjoiODJiZT... ) HHH-15551 ( https://hibernate.atlassian.net/browse/HHH-15551?atlOrigin=eyJpIjoiODJiZT... ) error when collection-valued property is missing a @OneToMany/@ManyToMany annotation ( https://hibernate.atlassian.net/browse/HHH-15551?atlOrigin=eyJpIjoiODJiZT... ) Issue Type: Bug Assignee: Unassigned Created: 26/Sep/2022 05:59 AM Priority: Major Reporter: Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) After the introduction of support for the SQL array type, the error message if you forget to add an @XxxToMany annotation got much worse: it now complains about a missing JDBC type mapping for ARRAY. This is a pretty bad user experience.
