Hi all,

Kindly review small documentation fix in Locale.toString() method.

Bug : https://bugs.openjdk.java.net/browse/JDK-8025547

webrev: http://cr.openjdk.java.net/~rgoel/8025547/webrev.02/ 
<http://cr.openjdk.java.net/%7Ergoel/8025547/webrev.02/>

Fix: updated documentation of Locale.tostring() method to reflect '_' 
character instead of '-' in between script and extension fields of 
Locale string.
