Equivalences.identity()'s behavior does not match its Javadoc

[GoogleCodeExporter]

In com.google.common.base.Equivalences.equivalent()'s Javadoc:

http://code.google.com/p/guava-libraries/source/browse/trunk/src/com/google/comm
on/base/Equivalences.java?r=144#55

"{@link Equivalence#equivalent} returns {@code true} if both values are null"
--> but implementation throws NPE when 'a' is null.

"{@link Equivalence#hash} throws a {@link NullPointerException} if passed a 
null value"
--> but implementation returns 0 when passed a null value (because 
System.identityHashCode() returns 0 for null values)

Thanks :)
