public class AbstractSetType<T>
extends Object
implements org.hibernate.usertype.EnhancedUserType<Set<T>>

A Hibernate UserType for Sets that need conversion to/from Json. In the past, this has been handed with a JPA converter, but as of Hibernate 6, Sets are handled differently with conversion happening on the individual constituents, instead of the entire Set. This was causing issues with type discovery and conversion based on design expectations. Changing this case to a Hibernate UserType instead works around the issue, and returns the behavior for this type of field handling to what it was previously.
