>
> When calling addMutation or addMutations on a MockBatchWriter, the updates 
> stored in the mutation are iterated over then committed in the MockTable 
> class. 
> When this occurs in the TabletServerBatchWriter (eventually called from the 
> BatchWriterImpl), however, the mutation size is first checked and if the 
> mutation size is 0, an IllegalArgumentException is thrown.
> In practice, if you have code that tries to submit an empty mutation to a 
> BatchWriter, it will fail and throw an exception in the real world, but this 
> will not be caught in tests against MockAccumulo.
