Hi,
I verified that using java.locale.providers=COMPAT with java 9
makes the AKST to be parsed as America/Juneau
Is http://bugreport.java.com/ the correct way to file a jira?

Hi Clément,
The locale data, where those time zone names are derived
from, have been
switched to use Unicode Consortium's CLDR, instead of the
ones that are
previously used prior to JDK9. So there will be some
differences you may
encounter. However it seems not right to parse "AKST" to
SystemV time
zone. I'd appreciate it if you file a JIRA issue for this.
In the mean time, you can revert to the JDK8 behavior by
setting the
system property "-Djava.locale.providers=COMPAT" to the
command line.
HTH,
Naoto
