Thanks, note, the Locale.Builder also supports setRegion(), so I think we might have to reconsider some separate stuff there and where it behaves strange or unexpected try to help Java 9 to address some of that within the scope of Unicode or other standards.

The Builder pattern, used also in JavaFX is something worth keeping an eye on. Whether a final value type like java.util.Currency gets this as a static Currency.Builder, like in Locale, or a more consequent approach similar to JavaFX (with its interface Builder<T>) is preferable, let us discuss and see.
javafx.util.Builder could have potential for more than just JavaFX, but that either in the core or ext JSR certainly was a possible idea, too.

Speak soon,

Dear All

I was playing around with Locale extensions on JDK 7/8. There was some strange behavior with toString() and extension input validation.
Summarizing I was able to create Locale instances that were not valid as defined in the specs (with duplicate singletons or tags).
More details are described in my blog entry here:

For our use cases according formatting/parsing the mechanism implemented by the JDK looks for me far too restrictive, to be able to replace, what we have defined as of now int the format package.
