It's not your change but I just noticed this. Since we specifically test only for `CLDR` provider (as in `BasicTestLauncher`), I wonder we could remove this portion. Even if we do need this piece, it could be simplified as:

ids = Arrays.stream(ids).filter(tz -> !tz.equals(...)).toArray(String[]::new)
