querydsl: Collection .contains() not working anymore

Observed vs. expected behavior

The query that I wrote in the past previously was working with older Hibernate, now is not working.

Steps to reproduce

In the repository classes there are 3 methods and none of those is working:

[UserRepositoryImpl] findByUserRole_1()

org.hibernate.query.SemanticException: Operand of 'member of' operator must be a plural path

[UserRepositoryImpl] findByUserRole_2() Alternate where clause also throws exception:

org.hibernate.query.QueryArgumentException:
Argument [ROLE_ADMIN] of type [com.thevegcat.app.config.UserRole]
did not match parameter type [java.util.Set (n/a)]

[UserRepository] findByUserRole_3() This one also used to work and now throws exception:

java.lang.ClassCastException:
class org.hibernate.metamodel.mapping.internal.BasicAttributeMapping cannot be cast to class
org.hibernate.sql.ast.tree.from.TableGroupJoinProducer
(org.hibernate.metamodel.mapping.internal.BasicAttributeMapping and
org.hibernate.sql.ast.tree.from.TableGroupJoinProducer are in unnamed module of loader 'app')

                .selectFrom( user )
                .where(
                    new BooleanBuilder().and( user.roles.contains( userRole ) ).getValue()
                )
                .fetch();
    }
