2. A java stack trace (long error message) containing the following information:
• Error Please report the following error to your system administrator:
• errorpage.jsp. StackTrace is java.lang.IllegalArgumentException: can't parse argument number:
• Caused by: java.lang.NumberFormatException: For input string: "" => this is at the end of the message
•  

• In the b1408 release the hint labels were parameterized, so now the label value goes through a process in which place-holders like {0} are replaced with some available arguments.
• This process treats the above sequence (i.e. {}) as a place-holder, but since it doesn't see an argument index in between it throws an exception.

• The proper way to address this is to leverage the arguments that are now available for the label to use:
• 0 = Start character of the upper-case alphabet range
• 1 = End character of the upper-case alphabet range
• 2 = Start character of the lower-case alphabet range
• 3 = End character of the lower-case alphabet range
• 4 = Start character of the Arabic numerals range
• 5 = End character of the Arabic numerals range
• 6 = Non-alphanumeric character set (i.e. special characters) => most likely to cause the issue
• 7 = Other optional character set
• Most of the time 2 values are not updated for one or more locale (Non alphanumeric special characters and Other optional characters) so they must be updated manually. 

Resolution Steps:

1. Navigate to References > Georgraphy > Locales labels
2. Search for label ID  instruction.passwordvalidation.PasswordCharacterClassesRuleHint
3. Open in edit mode the one corresponding to the locale you are experiencing issues with and you may see something like this:
1.          
4. Replace the values highlighted as below and apply changes
5. The password must contain the following types of characters:<br><ol><li>English uppercase letters [{0}-{1}]</li><li>English lowercase letters [{2}-{3}]</li><li>Arabic numerals [{4}-{5}]</li><li>Non alphanumeric special characters {6}</li><li>Other optional characters {7}</li></ol>
1. NOTE: the value for "other optional character" may be missing from the label you are updating and may be added but as it is optional it is at your discretion.
6. It is recommended to verify the label value for all locales and update any locales which does not have the correct settings
7. Try login again and you should no longer receive the issue
