Claudio Martella commented on GIRAPH-124:
-----------------------------------------

1) Weird... I'll take a look at it.
2) To be honest I didn't remember what we had agreed exactly, but <= sounds 
reasonable.
                
> Combiner should return Iterable<M> instead of M or null.

> Currently VertexCombiner is expected to return a single message combining the 
> input messages, or null in case no message should be sent. The new expected 
> interface should return an Iterable<M>, possibly empty. The number of 
> elements in the returned Iterable is supposed to be smaller than the number 
> of input messages, by the initial definition of a Combiner (defined as a 
> function to reduce I/O by combining multiple messages into 1).
