SpringBootApplication can't start up with otel-javaagent v1.15.0 with opentelemetry-samplers.jar

Hi,
we build a custom-otel-javaagent based on otel-javaagent, SpringBootApplication failed to start up when upgrade to otel-javaagent v1.15.0 (see the error below):

Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'webMvcMetricsFilter' defined in class path resource [org/springframework/boot/actuate/autoconfigure/metrics/web/servlet/WebMvcMetricsAutoConfiguration.class]: Unsatisfied dependency expressed through method 'webMvcMetricsFilter' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'compositeMeterRegistry' defined in class path resource [org/springframework/boot/actuate/autoconfigure/metrics/CompositeMeterRegistryConfiguration.class]: Initialization of bean failed; nested exception is java.lang.LinkageError: loader constraint violation: loader 'bootstrap' wants to load interface io.opentelemetry.javaagent.shaded.io.opentelemetry.api.common.Attributes. A different interface with the same name was previously loaded by io.opentelemetry.javaagent.bootstrap.AgentClassLoader @7aec35a. (io.opentelemetry.javaagent.shaded.io.opentelemetry.api.common.Attributes is in unnamed module of loader io.opentelemetry.javaagent.bootstrap.AgentClassLoader @7aec35a, parent loader io.opentelemetry.javaagent.bootstrap.AgentClassLoader$JdkHttpServerClassLoader @300ffa5d)

I just simply included opentelemetry-samplers in examples/distro

implementation("io.opentelemetry.contrib:opentelemetry-samplers:1.15.0-alpha")

SpringBootSmokeTest failed.

Any idea or suggestion? Please let me know if you need a issue for this and which repo opentelemetry-java-instrumentation or opentelemetry-java-contrib should be used to open issue.

Looks like you have shaded opentelemetry-api in both boot loader and under inst/ (where it shouldn't be). Try adding implementation("io.opentelemetry.contrib:opentelemetry-samplers:1.15.0-alpha") to custom/build.gradle also in the same file add

    dependencies {
      exclude(dependency("io.opentelemetry:opentelemetry-api"))
      exclude(dependency("io.opentelemetry:opentelemetry-context"))
      exclude(dependency("io.opentelemetry:opentelemetry-semconv"))
    }

inside shadowJar. Hopefully this way you'll get classes from opentelemetry-samplers in inst/ and won't get the classes that are supposed to be in boot loader.
