Here is an example using @JavaType annotation
Encountering the same issue on both id and non id fields

 org.hibernate.QueryException: Parameter 1 of function max() has type COMPARABLE, but argument is of type java.time.YearMonth

@MarcoBelladelli I understand that this is not exactly the same (same error, but using type insteand of converter) Do you want me to open a distinct issue ?
