ComparisonChain throws NullPointerException #500

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
...when comparing null values, unless using a nullsFirst or nullsLast 
comparator.

If this is intentional, this behavior should perhaps be documented better, as 
it differs from the Commons Lang CompareToBuilder, from which some people might 
be migrating.

It's universally true in Guava that if a method parameter (of reference/array 
type) isn't annotated @Nullable, it won't accept null (and will throw NPE).  I 
understand the suggestion that it might be worth calling out explicitly here 
anyway, but... I don't personally think it should need to be.
