I'm working on camel-quarkus debezium-mongodb -connector extension.
Quarkus mongodb client uses driver 4.x (see https://github.com/quarkusio/quarkus/blob/master/bom/runtime/pom.xml#L161)
Debezium uses driver of version 3.12.2.
This unfortunatelly doesn't seem to be backcompatible, I'm getting a lot of java.lang.NoClassDefFoundError, because of different packages and missing classes.

Upgrading version of mongodb driver will allow to create camel-quarkus extension.
