Github user osma commented on the issue:
https://github.com/apache/jena/pull/237
I agree with the other commenters, the general order should be (lang, lex)
to avoid potentially inconsistent ordering. Also the language tag may not match
any Locale. We also need to have unit tests that verify that the code works in
corner cases like this.
But what about subtags like `en-US` and `en-GB`? If the language tag is the
primary sort key, then all `en-GB` values would sort before `"a"@en-US`, which
I think would be confusing for most users.
The sort order and collation locale could be based on just the main tag
(`en` in this case) ignoring the subtags, but I'm quite sure there is some
language subtag out there in the world that requires a different collation
order from that of the main language...
