mvn clean package -DskipTests

Run without javaagent is normal.

java -jar target/demo-0.0.1-SNAPSHOT.jar

Output:

====begin
=====MyAddressResolver
addresses = [/127.127.10.1]

Run with javaagent is incorrect.

java -javaagent:opentelemetry-javaagent.jar \
      -Dotel.java.disabled.resource-providers=io.opentelemetry.instrumentation.resources.HostResourceProvider \
      -jar target/demo-0.0.1-SNAPSHOT.jar
