In JVM mode it doesn't throw any runtime exception. For running in JVM mode, run:

./mvnw install

java -jar target/quarkus-jsonb-starter-1.0-SNAPSHOT-runner.jar

Here it is allowing to have jsonb column in our model(known_fruits).

Run Quarkus as a native application

./mvnw install -Dnative

./target/quarkus-jsonb-starter-1.0-SNAPSHOT-runner

Here we are getting runtime exception mentioned in the description.
