Description

Encountered http language issue in Apple IOS recently:

• After they upgrade to IOS9
• If they enable Chinese input

When HTTP request initiated from IOS 9, there will have additional HTTP Header for "Accept-Language", and if the Chinese Input is enable, the header would look like: "Accept-Language: en-GB;q=1, zh-Hans-SG;q=0.9, en-SG;q=0.8".

Somehow the locale with "variants" is not support in apache CXF, and Illegal locale exception throw.

• Line #280.
• Using version 2.7.5 but the same issue still remain in 3.1.0

Quick fix is much appreciated. Thank you
