wildfly 23.0.1.Final with jaegertracing exception

I am running on Wildfly 23.0.1.Final (openjdk 11) under Centos 8.

I am not using opentrace in my application at all and i also did not add any jaeger dependency. Whenever i look in the logs, i often get an excpetion(Level: Warn) the looks like the following:

These messages fill the logfiles and i do not know how to disable the unwanted opentrace feature. I was not able to find something on google concerning this strange exception. Does anybody has some idea?

best regards

Solution 1:

If you don't use it, you can do something like the following in the CLI:

/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=jaeger:write-attribute(name=sampler-param, value=0)

Another solution is to remove the opentracing subsystem, install jaeger or wait for a release of WildFly with a fix for https://issues.redhat.com/browse/WFLY-14625
