500 Response (internal server error) and JasperReports Server login page does not work with Firefox and specific locale

Issue:

In a Firefox web browser, if you go to the log in and you have a specific locale (in this instance, it was the Dutch locale), a 500 Response (internal server error) appears and the JasperReports Server log in page does not work. Nothing works on the JasperReports server login page.

Solution:

This specific issue is caused by the file jquery.ui.datepicker-nl.js (this will be a specific locale. The Dutch locale is nl-NL). That specific file is located here:

C:Jaspersoftjasperreports-server-7.1.0apache-tomcatwebappsjasperserver-proscriptsbower_componentsjquery-uiuii18njquery.ui.datepicker-nl.js

The two occurrences of $.datepicker.regional.nl should be $.datepicker.regional['nl']. Once these changes have been made, a server restart will have to be made for the changes to take effect.
