Opentelemetry server templating does not work with template in class Path annotation

[hacst]

Describe the bug

I'm not sure whether this should even be allowed, but when adding a Path annotation with a template parameter to a class the server span contains the actual path of the request instead of the templated version.

According to @kenfinnigan it is worth figuring out what is supposed to happen here.

Expected behavior

Either Quarkus should complain about the template parameter in that place or the template should be correctly replaced.

Actual behavior

The actual url without replacement is used as the name of the server span.

To Reproduce

The problem is reproducible with a resource similar to:

@Path("/tracing/filter/{dummy}")
public static class TestResource {
  @GET
  public String get(@PathParam("dummy") String dummy) {
    // ...
  }
}

The resulting name of the span has the full path of e.g. /tracing/filter/1234 instead of the template /tracing/filter/{dummy}.

in contrast templating is working fine with

@Path("/tracing")
public static class TestResource {
  @GET
  @Path("/filter/{dummy}")
  public String get(@PathParam("dummy") String dummy) {
    // ...
  }
}

From a brief look it's valid for @Path on a class to have templated values, so looks like a bug in determining templated paths.

Yes, it is valid - albeit not widely used :)
