Problem launching an application using spring-cloud-azure-starter-active-directory 4.0.0

Question

Hello everyone,

We are currently working on a project using :

• Java 8
• Spring Boot 2.2.4
• Spring 4.3.17
• Maven 3.9.6

As part of an initial migration from spring boot 2.2.4 to 2.5.0, we had to upgrade the azure-spring-boot-starter-active-directory version successively from 2.3.5 to 4.0.0. From version 4.0.0+, we noticed that the dependency had changed name to spring-cloud-azure-starter-active-directory, which starts at version 4.0.0, so we switched dependencies to continue our upgrade.

We made the necessary changes indicated by the migration guides for both Spring/Spring Boot and azure-spring-boot-starter/spring-cloud-azure-starter.

We are now in the following configuration:

• Spring Boot 2.5.0
• Spring 5.3.7

We declare the following dependencies

• spring-boot-starter-parent 2.5.0 (parent in pom.xml)
• spring-boot-dependencies (parent of spring-boot-starter parent)
• spring-boot-starter-oauth2-client (version defined via spring-boot-dependencies)
• spring-cloud-azure-dependencies 4.0.0 (via dependencyManagement section in pom.xml)
• spring-cloud-azure-starter-active-directory (version defined via spring-cloud-azure-dependencies)

Also, we do not deploy our application through Azure Spring Cloud but through our own deployment system.

After making all the changes required for version upgrades, the project build via "mvn clean install" works.

However, when we launch the application, we encounter the following error:

Do you have any ideas as to what might be causing this error? Has the use of eventhubs become mandatory? If necessary, we can provide more information.

Thank you in advance.
