Issue with springboot v3.3 - Application fails to start

[ashishqcs]

I recently upgraded to springboot 3.3, after which the app is failing during startup. Service is hosted on gcp. Error:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [zipkin2.reporter.AsyncReporter]: Factory method 'stackdriverReporter' threw exception with message: Receiver class zipkin2.reporter.stackdriver.StackdriverSender does not define or inherit an implementation of the resolved method 'abstract zipkin2.reporter.Encoding encoding()' of interface zipkin2.reporter.BytesMessageSender.

I am using following tracing dependencies:

  implementation 'com.google.cloud:spring-cloud-gcp-starter-trace'
  implementation 'io.micrometer:micrometer-tracing-bridge-brave:1.3.0'
  implementation 'com.google.cloud:spring-cloud-gcp-starter-metrics'

I checked dependency tree and noticed all zipkin / brave related dependencies are on latest version available.

for eg: zipkin-reporter-java v3.4

Any idea on why this might be happening ?

I think the cause is identified here https://github.com/spring-projects/spring-boot/issues/40914 already
