Several traces created in Jaeger for just one method call --------------------------------------------------------- Key: WFLY-13866 URL: https://issues.redhat.com/browse/WFLY-13866 Project: WildFly Issue Type: Bug Components: MP OpenTracing Affects Versions: 21.0.0.Beta1 Reporter: Fabio Burzigotti Assignee: Emmanuel Hugonnet Priority: Critical Fix For: 21.0.0.Beta1 I am migrating one opentracing/fault-tolerance test from Thorntail TS [1] and I noticed that Wildfly SNAPSHOT is behaving differently with respect to what in the subject. The test is pretty simple, deploying a REST app which makes use of injected service which in turn leverages microprofile opentracing (via API) and fault-tolerance (via annotations). The test executes the following 2 methods in the given order: - call {{hello}}, which is synchronous and is throwing an exception, hence failing and gets called again then ending up with the fallback. This generates 1 trace with 4 spans in Jaeger and the behavior is consistent between TT and WildFly - call {{helloAsync}}, which is asynchronous and is throwing an exception, hence failing and getting called again (asynchronously?) then ending up with the fallback. This generates the following traces in Jaeger: TT: 1 trace with 4 spans WildFly: 4 separate traces , i.e. the one for the REST endpoint GET method, two for the {{helloAsync}} calls and one for the fallback.
