PersistentDispatcherFailoverConsumerTest.testAddRemoveConsumer also happend
this exception.
```
org.mockito.exceptions.misusing.WrongTypeOfReturnValue:
BrokerService 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.
