[Camel 3.5] OpenTracing integration test fails with Camel 3.5.0-SNAPSHOT

[jamesnetherton]

Until now we seem to have avoided OpenTracing API incompatibilities between 0.31.0 (used by Quarkus) & 0.33.0 (used by Camel). The Camel OpenTracingTracer now invokes a method that is not present in 0.31.0, hence we see:

AFAIK - Quarkus will not move to OpenTracing 0.33.x until MicroProfile OpenTracing is upgraded to 2.0.

[davsclaus]

They are on 0.33 on their master branch
https://github.com/eclipse/microprofile-opentracing/blob/master/pom.xml#L38

[davsclaus]

Maybe in the mean time we can make OpenTracingTracer in camel use the older api if its possible

[davsclaus]

Quarkus 1.7 seems to be going with MP 1.3.3 that uses the older 0.31.0 version.

So we may look at making camel-opentracing use the older API if possible and then upgrade to 0.33+ later.

[davsclaus]

This is only relevant when upgrading to Camel 3.5, and for quarkus 1.7 we can stay on camel 3.4.2 release.

[davsclaus]

Okay we have dropped back to 0.31.0 version

[jamesnetherton]

I verified this is fixed with the latest Camel 3.5.0 SNAPSHOT.
