Another similar scenario that previously worked with `camel-opentelemetry`
is JAX-RS services:
This:
```java
@Path("/trace")
@GET
@Produces(MediaType.TEXT_PLAIN)
public String traceRoute() {
return template.requestBodyAndHeaders("direct:start", null, headers,
String.class);
}
```
Would create a span hierarchy like:
```
|--- JAX-RS service
|------- direct:start
```
With `camel-opentelemetry2`, the spans are disconnected. To make it work you
have to hack the traceparent header:
```java
@Path("/trace")
@GET
@Produces(MediaType.TEXT_PLAIN)
public String traceRoute() {
Map<String, Object> headers = new HashMap<>();
headers.put("traceparent", Span.current().getSpanContext().getSpanId());
return template.requestBodyAndHeaders("direct:start", null, headers,
String.class);
}
```
