Yes, I mentioned this on the original review:
https://git.openjdk.java.net/jdk/pull/602

US/Pacific-New was only ever just a link to America/Los_Angeles,
rather than an actual definition like those in systemv &
jdk11_backward.  We could always add it to jdk11_backward if it
becomes apparent people depend it, but, in the unlikely event someone
is, it's much preferable that they just switch to using
America/Los_Angeles directly.

This wouldn't be the first time zones have been removed. I've seen
it happen in previous updates. The only difference here is the file,
which only contained a single zone, is removed as well.
