IllegalArgumentException invalid year value



You see IllegalArgumentException in the logfiles. Upon research, it appears the issue is related to the formatting of a date file with the following Function: @(Pega-RULES:DateTime).CurrentDate('YYYYMMDDTHHMMSS.QQQ', 'GMT').

Error Messages

javax.ejb.EJBException: nested exception is: java.lang.IllegalArgumentException: Invalid year value

Steps to Reproduce

Enter data in the UI and continue through the flow.

Root Cause

The root cause of this problem is a defect in customer application code/rules. The date format string had incorrect case for some of the date components. 'Y' should be 'y'.


This issue is resolved through the following local change:  The date format string was dropped.  Use of the correct Java date format string would have worked too.
