>From https://builds.apache.org/job/PreCommit-HBASE-Build/9306//testReport/org.apache.hadoop.hbase.master/TestAssignmentManager/testClosingFailureDuringRecovery/
'incCount' is a *void method* and it *cannot* be stubbed with a *return value*!
Voids are usually stubbed with Throwables:
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. The method you are trying to stub is *overloaded*. Make sure you are calling the right
overloaded version.
2. Somewhere in your test you are stubbing *final methods*. Sorry, Mockito does not verify/stub
final methods.
3. 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.

incCount() should be properly stubbed.
