Combination of rest-client and smallrye-opentracing ends with NPE when running generated tests

Describe the bug

Combination of rest-client and smallrye-opentracing ends with NPE when running generated tests

Using Quarkus 2.6.1.Final, test is passing when smallrye-opentracing is commented out.
Seems this is not a new regression, was able to reproduce on Quarkus 2.2.5.Final.

CDI: programmatic lookup problem detected
-----------------------------------------
At least one bean matched the required type and qualifiers but was marked as unused and removed during build

Stack frame: io.quarkus.resteasy.common.runtime.QuarkusConstructorInjector.construct(QuarkusConstructorInjector.java:35)
Required type: class io.quarkus.smallrye.opentracing.runtime.QuarkusSmallRyeTracingDynamicFeature
Required qualifiers: [@javax.enterprise.inject.Default()]
Removed beans:
	- CLASS bean  [types=[class io.quarkus.smallrye.opentracing.runtime.QuarkusSmallRyeTracingDynamicFeature, interface javax.ws.rs.container.DynamicFeature], qualifiers=null]
Solutions:
	- Application developers can eliminate false positives via the @Unremovable annotation
	- Extensions can eliminate false positives via build items, e.g. using the UnremovableBeanBuildItem
	- See also https://quarkus.io/guides/cdi-reference#remove_unused_beans

Expected behavior

mvn clean verify passes

Actual behavior

mvn clean verify execution fails with NPE

How to Reproduce?

Generate the project:

• mvn -Dquarkus.platform.artifact-id=quarkus-bom io.quarkus:quarkus-maven-plugin:2.6.1.Final:create -DprojectGroupId=io.quarkus.qe -DprojectArtifactId=rest-client-smallrye-opentracing -DprojectVersion=1.0.0-SNAPSHOT -DplatformGroupId=io.quarkus -DplatformArtifactId=quarkus-bom -Dextensions=rest-client,smallrye-opentracing

Run it:

• mvn clean verify -f rest-client-smallrye-opentracing

Output of uname -a or ver

No response

Output of java -version

I will take a look at this as @metacosm brought this to my attention via quarkiverse/quarkus-operator-sdk#174 which seems to share the same root cause
