Hibernate ORM with Multitenancy and TenantConnectionResolver default datasource

Describe the bug

When using Hibernate ORM with Multitenancy and a CustomTenantConnectionResolver like described here, I noticed that Quarkus does not start as long as I do not specify a jdbc url for the default datasource in the application.properties. Why isn't org.hibernate.engine.jdbc.connections.spi.MultiTenantConnectionProvider#getAnyConnection used for this? Or do you have to configure something else for this?

Expected behavior

Quarkus should start and use the default datasource specified via getAnyConnection.

Actual behavior

Quarkus does not start or you need to define the datasource in the application.properties

To Reproduce

Link to a small reproducer (preferably a Maven project if the issue is not Gradle-specific).

Or attach an archive containing the reproducer to the issue. code-with-quarkus.zip

Steps to reproduce the behavior:

Without jdbc url defined start the the application -> application won't start
Add an jdbc url to application.properties and start the applicaytion -> application will start but uses the the datasource from application.properties and does not resolve it programmatically

Configuration

# Add your application.properties here, if applicable.
quarkus.hibernate-orm.database.generation=none
quarkus.hibernate-orm.multitenant=DATABASE
quarkus.datasource.devservices=false

quarkus.datasource.db-kind=postgresql
#quarkus.datasource.username=postgres
#quarkus.datasource.password=test

#quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/postgres
