combination of treats (

)

While working on the upgrade to WildFly 27, we ran into the issue below. The case runs
fine on Hibernate ORM 5.6.14 and 5.3.28 (on WildFly 26.1.2).
A combination of a select of a treated root, a predicate on property on the treated root
and a predicate on a property on a join via a the treated root confuses
{{visitJunctionPredicate}}. It adds null to the {{conjunctTreatUsagesList}}, but because
{{hasAnyTreatUsage}} is also set, it dereferences the elements in the list, triggering a
{{NullPointerException}}.
