Hi Koen,
thx, I got it now, the groupId and artifactId has to be changed too. I’m getting now:
package dbo;
// Generated Jul 14, 2026, 11:36:36 AM by Hibernate Tools 7.4.5.Final
but it still generates @GenericGenerator and @GeneratedValue annotations on the PK=FK column property, resulting in the same 6.x runtime mapping exception.
