Compatibility with opentelemetry-spring-boot-starter and Spring Boot versions

[c4rth]

Describe the bug

I have a Spring Boot application using version 3.1.12.

When I'm using opentelemetry-spring-boot-starter and opentelemetry-exporter-zipkinfrom opentelemetry-instrumentation-bom version 2.9.0, the application doesn't start.

I need to downgrade opentelemetry-instrumentation-bom to version 1.32.1 and opentelemetry-spring-boot-starter to version 1.32.1-alpha for the application to start.
Yet the documentation says that 'The OpenTelemetry Spring Boot starter works with Spring Boot 2.6+ and 3.1+'

rem: If I update the Spring Boot version 3.3.4, there is no more error (but I have to use 3.1.12)

Steps to reproduce

• Create a Spring Boot application using version 3.1.12
• In the pom.xml
  • add dependencyManagement

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.opentelemetry.instrumentation</groupId>
            <artifactId>opentelemetry-instrumentation-bom</artifactId>
            <version>2.9.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

• add dependencies for opentelemetry-spring-boot-starterand opentelemetry-exporter-zipkin

 <dependency>
     <groupId>io.opentelemetry.instrumentation</groupId>
     <artifactId>opentelemetry-spring-boot-starter</artifactId>
 </dependency>
 <dependency>
     <groupId>io.opentelemetry</groupId>
     <artifactId>opentelemetry-exporter-zipkin</artifactId>
 </dependency>

• start the application

Expected behavior

No error

Actual behavior

The applications fails to start with this stacktrace:

Looks like a version conflict for zipkin library. You should check your dependencies and see what version of io.zipkin.reporter2:zipkin-reporter you have and what enforces that version. Using a newer version of that library should help.
