JEP 405 update

[Gavin Bierman]

Dear experts,

Just to let you know that I have updated JEP 405:

https://openjdk.java.net/jeps/405 

You will see that we have removed the array patterns from this JEP (and it has
been retitled accordingly). We're still committed to supporting a direct pattern
form for arrays, but given our tight schedule and a number of queries about the
exact syntactic form for array patterns, we think we'll be better off decoupling
them from JEP 405, and releasing them in a future patterns JEP.

Comments welcomed!
Gavin
