I saw your pull-request, still not sure I can correlate it to my initial problem. I’ll appreciate if you shed more light. Any idea for a workaround, hack, what-ever, cause this “ class TaskServiceDocument<E extends Enum<E>> “ is a base legacy class I’m not in position to touch and it is working fine with current Hibernate version. Any idea when there might be an official fix, if planned at all? I’m open to jump into some sort of live session, such as zoom, for the sake of efficiency.
