URL: https://github.com/apache/pulsar/issues/13570
PersistentTopicTest is flaky. The setup() test method fails sporadically.

2021-12-30T14:52:26,643+0800 [metadata-store-772-1] ERROR org.apache.pulsar.metadata.impl.AbstractMetadataStore - Failed to process metadata store notification
org.mockito.exceptions.misusing.WrongTypeOfReturnValue:
BrokerService$MockitoMock$699853984 cannot be returned by getPulsarResources()
getPulsarResources() should return PulsarResources
***
If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception *might* occur in wrongly written multi-threaded tests.
Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies -
- with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method.
