As best as I can determine the name is either derived from the the name used by Guava for the same predicate, "notNull", or the names derives from the name "requireNonNull" in that this method doesn't require that the reference be non-null. The EG hasn't been concerned that this method doesn't use the "is" prefix.

Do we need nonNull/isNotNull() at all, as it's always !isNull()?
Anyway I would prefer isNotNull().
