Hi Niclas, In this commit[1] we make ResourceUsage in your report immutable. It seems that in your final class loading result, it loads 2.9.1's LoadManagerShared and 2.10.0's ResourceUsage, where 2.9.1 code assume field 'usage' is mutable.
Could you try to check the effective classpath, especially which version of pulsar-broker and pulsar-client-admin-api is in use? Best, tison.
