I have made a retreat on this just to add the two missing equals methods:

  http://cr.openjdk.java.net/~psandoz/jdk9/JDK-8141409-Arrays-equals-comparator/webrev/ <http://cr.openjdk.java.net/~psandoz/jdk9/JDK-8141409-Arrays-equals-comparator/webrev/>

I propose to revisit the overall null-handling semantics, especially for Comparable[] accepting methods, at a later date.
