Hello.
nonNull could be renamed into isNonNull, else people might use it instead of requireNonNull, especially if they are already used to a pre-Java 7 requireNonNull that would be called nonNull. (example: http://grokbase.com/p/openjdk/core-libs-dev/111tbha823/code-review-7012540-java-util-objects-nonnull-incorrectly-named ) It would also be more consistent with isNull. -Jeff
