Postgres JSONB not working with Upgrade to SpringBoot Version 3.0

I have a Kotlin SpringBoot project. It's a relatively simple API that persists data to a Postgres JsonB database. I am using the @TypeDef annotation on my entity class, but after upgrading to SpringBoot Version 3.0 with hibernate-core:6.1.7.Final this annotation is no longer available.

Here is my entity class::

import com.vladmihalcea.hibernate.type.json.JsonBinaryType
import jakarta.persistence.Column
import jakarta.persistence.Entity
import jakarta.persistence.Id
import jakarta.persistence.Table
import org.hibernate.annotations.Type
import org.hibernate.annotations.TypeDef // not available with latest hibernate-core

import java.io.Serializable
import java.security.SecureRandom
import kotlin.math.abs

@Entity
@Table(name = "myTable")
@TypeDef(name = "jsonb", typeClass = JsonBinaryType::class) // not available :(
data class RecommendationEntity(
  @Id
  open var id: Long = abs(SecureRandom().nextInt().toLong()),
  @Type(type = "jsonb")
  @Column(columnDefinition = "jsonb")
  var data: MyModel
)

data class MyModel(
  // nothing special just a POJO
) : Serializable

And here is my build.gradle.kts::

plugins {
  id("XXXXXXXXXX.gradle-spring-boot") version "5.0.1" // in house plugin thatcopies 3.0.2
  kotlin("jvm") version "1.8.10"
  kotlin("plugin.jpa") version "1.8.20-Beta"
  kotlin("plugin.spring") version "1.8.20-Beta"
}

jacoco.toolVersion = "0.8.8"

configurations {
  testImplementation { exclude(group = "org.junit.vintage") }
}

testSets {
  "testSmoke"()
}

// allOpen {
//  annotations("javax.persistence.Entity")
// }

What I've tried::

• Using hibernate-core:5.6.3.Final instead of 6.1.7.Final where @TypeDef is available, but that gives the error -

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Class org.springframework.orm.jpa.vendor.SpringHibernateJpaPersistenceProvider does not implement the requested interface jakarta.persistence.spi.PersistenceProvider

• Looking through the various options here - how to store PostgreSQL jsonb using SpringBoot + JPA? there isn't any help specific to upgrading to SpringBoot V3.0

I'm quite stumped on this one, and am beginning to think that SpringBoot V3.0 doesn't support Postgres JsonB Nosql :( Can anybody help me with a solution? Or perhaps confirm whether Postgres JsonB Nosql is indeed not supported in the new SpringBoot version? Thanks
