>   // BUG here
>   BlockPoolSlice.reInitializeAddReplicaThreadPool();
>   Configuration cnf = new Configuration();
>   int poolSize = 5; 
>   ...

> _addReplicaThreadPool_ may not have been initialized and is null, if we run testAddRplicaProcessorForAddingReplicaInMap unit test as an individual unit test.
