I investigated some usage of this method on GitHub:

https://github.com/search?q=%22lowerCaseMode%28true%29%22+language%3AJava&type=code

In the use cases I see, it seems that no one wants to rely on the default locale.

However, while I think this corrects the behavior, this caused a change in the behavior of the API, so a CSR may be required. I don't want to debate this in this PR, so I'll revert this change and open a new PR in the future.
