Tracer on Scheduler Tasks - Spring boot

[groversi]

I'm trying to instrument Jaeger on spring app, with a scheduler. But the behavior of Tracer is little bit strange from an app with api's. Jaeger does not create a new Trace when the scheduler starts, Tracer.activeSpan() returns null, and the uber-trace-id is not propagated to other services.

Is there anyone who did an instrumentation on a Spring scheduler?
