```shell
mvn clean package -DskipTests
```

Run without javaagent is normal.
```shell
java -jar target/demo-0.0.1-SNAPSHOT.jar
```

Output:
```shell
====begin
=====MyAddressResolver
addresses = [/127.127.10.1]
```

Run with javaagent is incorrect.
```shell
java -javaagent:opentelemetry-javaagent.jar \
      -Dotel.java.disabled.resource-providers=io.opentelemetry.instrumentation.resources.HostResourceProvider \
      -jar target/demo-0.0.1-SNAPSHOT.jar
```

Output:
```shell
