-ICU4J Locale Service Provider uses a special Locale variant value for overriding Java's
-Locale service support. In this release, the default value of the special variant was
-changed to "ICU4J" (previously, it was "ICU"). For example, with JDK Locale("en", "US", "ICU4J"),
-ICU service implementation is used instead of Java's stock implementation for Locale("en", "US").
-This change had made for BCP 47 conformance. The special variant value can be changed by
-editing a properties file included in the ICU4J Locale Service Provider jar file.
