Springboot v3.3.0 - application failing during startup due to zipkin / brave tracing version upgrade

I recently upgraded to springboot v3.3, after which the app is failing during startup. Service is hosted on gcp. Error:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate

I am using following tracing dependencies:

  implementation 'com.google.cloud:spring-cloud-gcp-starter-trace:5.3.0'
  implementation 'io.micrometer:micrometer-tracing-bridge-brave:1.3.0'
  implementation 'com.google.cloud:spring-cloud-gcp-starter-metrics':5.3.0

Any idea on why this might be happening ?

Looks like spring-cloud-gcp-starter-trace is using Brave 5. They need to update it to Brave 6.
