Opentracing fails to load on EAR deployment

wildfly 18, an EAR application (ovirt-engine ), I'm trying to enable opentracing, and failing.

I added this to our xml:

```
<extension module="org.wildfly.extension.microprofile.opentracing-smallrye"/>
...
<subsystem xmlns="urn:wildfly:microprofile-opentracing-smallrye:1.0"/>
```

Exported Jaeger environment vars:
```
export JAEGER_SERVICE_NAME=ovirt-engine
export JAEGER_REPORTER_LOG_SPANS=true
export JAEGER_SAMPLER_TYPE=const
export JAEGER_SAMPLER_PARAM=1
```

And debugged the `TracerProducer` which throws:

```

The deployment structure is:
