Releasing a version with a pre-filled release date is giving an invalid date error for non-US clients

Steps to reproduce:

1. Create a new version, set a release date
2. Set client language to german
3. Click Release
4. Note: Date field now shows localized date format
5. Press Release

Observed behavior: "Please enter the date in the following format: d/MMM/yy"
Expected behavior: Jira should either accept the localized date format, or pre-fill the form with the expected date format.

Recommend to test in your staging/testing environment first.
Workaround:

1. Ensure date time format have been edit via Administration > System > Look and Feel > Date/Time Format

   • Complete Date/Time Format : dd/MM/yyyy hh:mm a 
     Day/Month/Year Format : dd/MM/yyyy (eg: 01/01/2013)
     

2. Ensure you have edit javascript date time picker via Administration > System > General Configuration > Advanced

   • jira.date.picker.java.format : dd/MM/yyyy (eg: 01/01/2013)
     jira.date.picker.javascript.format : %d/%m/%Y 
     jira.date.time.picker.java.format : dd/MM/yyyy h:mm a 
     jira.date.time.picker.javascript.format : %d/%m/%Y %H:%M 
     

Note: If you want to change date (01/01/2013) to (01.01.2013), just replace the character ( / ) to ( . )
