I've encountered a problem with application startup with: - org.springframework.boot:spring-boot-starter-actuator:3.2.5 - io.micrometer:micrometer-tracing-bridge-brave:1.3.0 - io.zipkin.brave:brave:6.0.3 (transitive from micrometer-tracing-bridge-brave)
I think the crucial part of the exception I'm getting is:
Caused by: java.lang.UnsupportedOperationException: As of Brave 5.18, you must implement PropagationFactory.get()
at brave.propagation.Propagation$Factory.get(Propagation.java:95) ~[brave-6.0.3.jar:?]
at brave.Tracing$Default.<init>(Tracing.java:371) ~[brave-6.0.3.jar:?]
at brave.Tracing$Builder.build(Tracing.java:341) ~[brave-6.0.3.jar:?]
at org.springframework.boot.actuate.autoconfigure.tracing.BraveAutoConfiguration.braveTracing(BraveAutoConfiguration.java:123) ~[spring-boot-actuator-autoconfigure-3.2.5.jar:3.2.5]
Downgrading to io.micrometer:micrometer-tracing-bridge-brave:1.2.6 seems to solve the issue.
As far as I was able to track the problem down it seems to be related to the implementation of org.springframework.boot.actuate.autoconfigure.tracing.CompositePropagationFactory being incompatible with io.zipkin.brave:brave:6.x.x. The incompatibility is related to the lack of an implementation of the method mentioned in the exception message.

Spring Boot 3.2.x does not support Brave 6.0. Support is coming in Spring Boot 3.3 that will be released later this week.
