When language is set to French, date picker bug

Summary

When you attempt to release a version in JIRA with your language set to French, the date box will autocorrect the month with a dot (ex : oct.), but the validation of the box needs the month without a dot (ex : oct). This makes it impossible to release a version.

Steps to Reproduce

1. Set profile or system language to French
2. Attempt to select a Start Date or End Date when creating a version in a project

Expected Results

The format should follow the date picker format set in Advanced Configuration.

Actual Results

Even when selecting the date from the calendar popup, the month will always have a "." at the end, which the system will not accept. Attempting to change it does not work, as when you click out of the box, the "." reappears.

Workaround

Change the Date format parameters (or contact Atlassian Support to do this for Cloud customers) to a format that only uses numerals for months, such as to d/MM/yy

Perform the change in the version date;

Change back de language to French.
