I'm getting

@laurit can you give me a hint?

@laurit can you give me a hint?

I thin you forgot to actually use the ApplicationOpenTelemetry155Incubator that you added. Have a look at

opentelemetry-java-instrumentation/instrumentation/opentelemetry-api/opentelemetry-api-1.0/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/opentelemetryapi/ApplicationOpenTelemetry.java

Line 22 in 39137d1

OpenTelemetry instance = getOpenTelemetry127();

Thanks @laurit - can you check if this PR together with the SDK PR make sense (see ticket description)?
