Really hope that someone from Hibernate team will confirm and share what’s the plan for the fix. I came up with some sort of partial fix moving all the props from the Generic class to “artificially“ introduced parent class that is NOT generic. However for the Generic property that’s not an option. @MappedSuperclass public static class TaskServiceDocumentFix extends MultiTenantDocument { // Now this prop is part of the parent non-generic class and is OK @Type(JsonBinaryType.class) @Column(columnDefinition = "jsonb") public ServiceTaskCallback serviceTaskCallback; } @MappedSuperclass public static class TaskServiceDocument<E extends Enum<E>> extends TaskServiceDocumentFix { // However this does not work @Enumerated(EnumType.STRING) public E taskSubStage; } ( https://hibernate.atlassian.net/browse/HHH-16122#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16122#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
