-----------------------------------
Summary: There is a bug in judging whether traits are different in
RelTraitSet#difference.
Key: CALCITE-5397

Affects Versions: 1.32.0
Environment: !image-2022-11-23-16-01-06-098.png!

I think
{code:java}
!thisTrait.equals(thatTrait){code}
should be used here instead of
{code:java}
!={code}

As shown in the figure below, the content of the two is consistent, but it is
currently judged to have a difference. !image-2022-11-23-16-06-11-621.png!
