CldrUtility.ifNull() --> Objects.requireNonNullElse​()

[markusicu]

We should shrink our dependence on CLDR code. In particular, CLDR has utility functions for which now exist standard library functions.

Specific example: We use CldrUtility.ifNull(x, y) which is a tiny utility, and AFAICT is the same as Java 9+ Objects.requireNonNullElse​(x, y).

Bonus: Look for standard replacements for other CldrUtility functions.

On the CLDR site, we should fix cases like that. That is,

• change the definition of CLDRUtility.ifNull to just call the Java method
• mark CLDRUtility.ifNull as deprecated
• refactor to remove all of its instances in CLDR code.

So can you bring any others of these (whether in CLDRUtility or elsewhere) to our attention? We can file an umbrella CLDR ticket to handle them.

Right. I filed CLDR-19414 for this same scope. If someone on either side finds more things to replace, please update both sides.

Perfect, thanks!
