NullPointerException for jsonb Postgres column

[heck-gd]

We're currently migrating a project to hibernate6 and ran into an issue. Our database server is PostgreSQL and we're using the io.hypersistence:hypersistence-utils-hibernate-63 package to get json/jsonb column support in Hibernate.

A simplified example looks like this:

import io.hypersistence.utils.hibernate.type.json.JsonBinaryType;
import org.hibernate.annotations.ColumnDefault;
import org.hibernate.annotations.Type;

import jakarta.persistence.*;
import jakarta.validation.constraints.NotNull;

public class TheData {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @NotNull
    @Type(JsonBinaryType.class)
    @Column(columnDefinition = "jsonb")
    @ColumnDefault("{}")
    private String info = "{}";
}

When running diffChangelog, this results in:

It logs [liquibase.ext] Found column info jsonb, but the parseType is an object where all fields are null, causing the exception.

hibernateColumn contains a value of type BasicValue which in turn has a resolution that contains the JsonBinaryType stuff, but Liquibase doesn't seem to pick up on it. The typeName field is not going to be set for such values.
