Hello Sherman, Masayoshi and other experts,

Can I ask for a JDK9 review for the 
sun/util/calendar/zi/TestZoneInfo310.java test failure [1] that was 
caused by incorrect handling of last rules for Africa/Casablanca time 
zone. This timzone has two last rules and three instant rules in a range 
of these last rules that causes incorrect instant transitions table 
generation. The proposed fix [2] solves this problem. Also there is a 
modification to test class that solves the issue with not optimized 
instant transitions with the same offset/saving values that are the last 
two in instant transitions table. And TestZoneInfo310.java is removed 
from problems list.

All tz related test were executed with no failures.
JPRT build/testing successfull for all platforms.

Best Regards,
