Motivation
It's necessary to keep OpenTelemetry libraries up-to-date. In Pulsar, OpenTelemetry was upgraded to 1.56.0 version in PR apache/pulsar#24994 . Since Pulsar deployments combine BookKeeper dependencies in the same classpath, it's necessary to upgrade OpenTelemetry in BookKeeper to be fully compatible. (There have been some minor API changes causing breaking changes in OTel since 1.45.0.)
