"Bailing out of neverEnding selector to avoid infinite loop" error when all PlanningEntity pinned and there are two @PlanningEntity classes

When "pin" feature of optaplanner used it throws"Bailing out of neverEnding selector (Filtering(FromSolutionEntitySelector(PersonAssignment))) to avoid infinite loop." error. This is checked both 7.32.0 final and also 7.44.0.Final versions.

Domain model consists of two @PlanningEntity(PersonAssignment and HotelOccupancyPerSlot), customShadowVariable and also TimeGrain. Gives this warning when all of the PersonAssignment entity pinned. It just log this warning and then nothing happens.
