Missing jaxrs span in Open Liberty

[fmhwong]

Describe the bug
Running a simple JAX-RS application in both WebSphere Application Server traditional and Open Liberty with the latest version of Agent.

I got 3 spans from WebSphere Application Server traditional version 9.0.5.12 on Java 8.

1. HTTP GET /properties
2. JAX-RS getProperties()
3. @WithSpan SystemResources.sleep()

However, I got 2 spans from Open Liberty version 23.0.0.1 on Java 11.

1. HTTP GET /properties
2. @WithSpan SystemResources.sleep()

The JAX-RS span is missing from Open Liberty.

Steps to reproduce

import java.util.Random;

import javax.enterprise.context.RequestScoped;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import io.opentelemetry.instrumentation.annotations.WithSpan;

@RequestScoped
@Path("/properties")
public class SystemResource {

    private static Random rand = new Random(); 
    
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getProperties() throws InterruptedException {
        sleep(rand.nextInt(500));
        return Response.ok(System.getProperties()).build();
    }

    @WithSpan
    private static void sleep(long ms) throws InterruptedException {
        Thread.sleep(ms);
    }
}

What did you expect to see?
Three spans should be created from Open Liberty.

What did you see instead?
Only two spans were created as described above.

What version are you using?
opentelemetry-javaagent version 1.23.0

Environment
Compiler: OpenJDK 11.0.11
OS: MacOS
Runtime (if different from JDK above): OpenJDK 11.0.17
OS (if different from OS compiled on): Ubuntu 20.04.5 LTS (Focal Fossa) in a container

OpenLiberty 23 uses Javarta EE 9: https://openliberty.io/docs/latest/jakarta-ee9-feature-updates.html
The app server probably does not contain the javax.* classes, it has jakarta.* classes instead.

Have you tried running the example above using the jakarta.ws.* annotations instead?

[fmhwong]

I was testing the above class with jaxrs-2.1 feature in Open Liberty 23.0.0.1. I also tested with the Jakarta EE 9 version of the app with restfulWS-3.0 feature in Open Liberty 23.0.0.1. None of them show the JAX-RS spans.

@fmhwong if you're able to troubleshoot this and send a PR to fix that would be much appreciated!

[fmhwong]

Someone has made a PR. I can test it when the fix is available.

The fix is working. Thanks for the quick turnaround!
