Hello there,
I faced on an issue concerning the date format in a JIRA Sevice Desk application.
I have configure my application threw advanced setting screen and change the following value:
- jira.date.picker.java.format to "dd/mm/yyyy".
- jira.date.time.picker.java.format to "dd/mm/yyyy".
But when i pick up a date on a custom field the date is displayed like this:
"18/mar/18"
And when i want to save my change, an error message is triggered as follow:
"Invalid date format. Please enter the date in the format "dd/mm/yyyy"."
I miss something but i dont found out where excacly.
Do you have any idea ?
Thank in advance for any tips or feed back 
Olivier
