Vasily Ivanov commented on COLLECTIONS-223:
-------------------------------------------

Henri,

I don't see any backwards compat issue with changing "void" return type to "Collection" unless someone calls that static addAll() method via reflection and relays on "java.lang.Void" to be a return type. I really doubt someone does that kind of things.

> Like MapUtils.putAll() method returns input map, CollectionUtils.addAll() methods should return the input collection.
> This will allow to init and populate collection at the same line:
> ArrayList inputs = (ArrayList) CollectionUtils.addAll(new ArrayList(), new String[] { "value1", "value2" });
