ICU4J: MF2: Change Directionality.of(ULocale ulocale) to use Locale

[proposed:2025-09-18] ICU4J: MF2: Change Directionality.of(ULocale ulocale) to use Locale

In the Sep. 11 meeting we approved promoting some of the MF2 public APIs to draft.

But Markus noticed that one method in Directionality uses ULocale.

The proposal is to change that API to take a Locale instead, for consistency with getLocale in MessageFormatter and setLocale in MessageFormatter.Builder.

Directionality {

    UNKNOWN,

    LTR,

    RTL,

    AUTO,

    INHERIT;

    public static Directionality of(ULocale ulocale);

}

Thank you,
Mihai
