4-letter patterns in Date Format Style no longer give full text style

[Naoto Sato]

Hi,

In your test case,

```
new Locale("en_US");
```

This will fall back to ROOT locale texts with CLDR (default since JDK9) 
where it differs from US English. Probably you may want to `new 
Locale("en", "US)` or preferably use `Locale.US` constant.
