Hi Ramanand,

Looks good to me. Glad that the number of files to review has decreased 
a lot :-)

> Summary:
> 	- This patch uses "vanguard" format tzdata from IANA (instead of rearguard format), as the enhancement bug[1] is fixed now. Many thanks to Naoto for this.
> 	- As per the latest changes to Palestine zone rules, the hard-coded checks for "Asia/Gaza" and "Asia/Hebron" are no more needed in ZoneInfoFile.java.
> 	  Because of those checks test/jdk/sun/util/calendar/zi/TestZoneInfo310.java was failing as mentioned in the bug comment[3].
> 	- test/jdk/java/util/TimeZone/TimeZoneTest.java is updated to set ZoneDescriptor.daylight value to "false" for BET zone id.
> 	- The patch has passed all the related testing including JCK.
> Notes:
> - As per the mail from tzdata maintainers[2] there is a possibility that Brazil might not abolish DST.
> - Since the enhancement bug[1] is not fixed in update releases, jdk13u will still use the rearguard format tzdata. A separate review request will be sent for the same.
