<i18n dev> RFR: JDK-8087104: DateFormatSymbols triggers this.clone() in the constructor

[Ramanand Patil]

Hi all,
Please review the fix for bug: https://bugs.openjdk.java.net/browse/JDK-8087104
Bug Description: DateFormatSymbols caches its own instance and calls this.clone() in the constructor. Because of this, any subclass implementation (which expects a field is always initialized to non-null in the constructor) will throw NPE in its overridden clone() method while using any instance variables which it assumed are initilaized in its contructor.
Webrev: http://cr.openjdk.java.net/~rpatil/8087104/webrev.00/
Fix: Instead of using its own instance for caching and calling clone in DateFormatSymbols, a nested class SymbolsCacheEntry is introduced.
 

Regards,

Ramanand.
