While searching for any report in Jasper Library, I am getting this error :" java.lang.IllegalArgumentException: Illegal pattern character 'r'". Everything was working fine until yesterday. Any idea about this?

I guess there is a field with illegal pattern on report. Check the fields' pattern on report by design window or search with 'pattern' on source window. Find the field and correct the pattern.
