I have the following azure spring dependencies:
  <properties>
            <azure-sdk.version>1.2.2</azure-sdk.version>
            <azure-spring.version>6.0.0</azure-spring.version>
  </properties>
 <dependency>
        <groupId>com.azure.spring</groupId>
        <artifactId>spring-cloud-azure-starter-keyvault</artifactId>
    </dependency>
  <dependency>
      <groupId>com.azure.spring</groupId>
      <artifactId>spring-cloud-azure-starter-active-directory</artifactId>
  </dependency>
    <dependency>
            <groupId>com.azure.spring</groupId>
            <artifactId>spring-cloud-azure-starter-storage-blob</artifactId>
     </dependency>
Those are using azure-spring version 6.0.0.
I also have the following ones needed for integration with Azure:
    <dependency>
        <groupId>com.azure.spring</groupId>
        <artifactId>spring-cloud-azure-dependencies</artifactId>
        <version>${azure-spring.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-dependencies</artifactId>
        <version>${spring-cloud.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
    <dependency>
        <groupId>com.azure</groupId>
        <artifactId>azure-communication-email</artifactId>
        <version>1.1.1</version>
    </dependency>
I think the error in particular is coming from spring-cloud-azure-starter-keyvault and on Spring Boot migration guide I found no advice about migrating Azure related dependencies: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide
I consulted the spring versions map https://github.com/Azure/azure-sdk-for-java/wiki/Spring-Versions-Mapping and I see none for the Spring Boot 4.0.0
Is Azure planning to launch a new version soon with additional support for this version of Spring Boot?
