Mongodb – Migrating to 'Morphia' from Hibernate OGM

I have been running MongoDB (5.0.7) for a number of years with Hibernate ORM & OGM. Currently using ‘org.mongodb:mongodb-driver-core:4.6.0‘. (2022.04.26)

Using WildFly 26.1.0.Final (Jakarta EE 8 Full) with OpenJDK 18.0.1. IntelliJ IDEA 2022.1, Gradle 7.4.2 & macOS Monterey 12.3.1.

I need to migrate to Jakarta 9. See "Hibernate OGM is not going to work with ORM 5.5 (the latest version requires ORM 5.3)." on:
How to use Hibernate ORM 5.5.x.Final with Jakarta 9 on wildfly-preview-25.0.0.Final

I am looking at using ODM ‘Morphia 2.2.6‘ (dev.morphia.morphia:morphia-core:2.2.6) and trying to run the ‘morphia/example/QuickTour.java’:

https://github.com/MorphiaOrg/morphia/blob/2.2.x/examples/src/test/java/dev/morphia/example/QuickTour.java

It compiles, but when I try & run it I get:

Exception in thread "main" java.lang.NoSuchMethodError: 'java.lang.String com.mongodb.connection.ClusterSettings.getDescription()'
    at com.mongodb.connection.DefaultClusterFactory.createCluster(DefaultClusterFactory.java:179)

    at com.mongodb.client.MongoClients.create(MongoClients.java:40)
    at dev.morphia.example.QuickTour.main(QuickTour.java:23)

Have also tried with:

 final Datastore datastore = Morphia.createDatastore(MongoClients.create("mongodb://localhost:27017"), "morphia_example");

Any suggestions? TIA.
