Answer 1

That valueSelector is SORTED, so it needs to cache (to be able to sort them). But caching with a @ValueRangeProvider per entity is not supported if I recall correctly.

This implies that the CH with a @ValueRangeProvider per entity only supports FIRST_FIT and FIRST_FIT_DECREASING, but not WEAKEST_FIT or STRONGEST_FIT. I believe there's a jira for this already (do link it here if you find it). We need to fix this.

Meanwhile: a workaround would be to not use SORTED, but already sort them in each entity's value range list.
