Romain Manni-Bucau commented on CSV-164: ---------------------------------------- yep: {code} A,B,C,A,b2,C 1,2,3,4,5,6 {code} A is twice a column but it is a valid CSV file - actually just renamed an export from a proprietary tool. > support duplicate headers > ------------------------- > > Key: CSV-164 > URL: https://issues.apache.org/jira/browse/CSV-164 > Project: Commons CSV > Issue Type: Bug > Reporter: Romain Manni-Bucau > > nothing prevents a CSV to have the same time the same header name so > validation at the end of org.apache.commons.csv.CSVFormat#validate should > likely disappear or should support a flag to disable it -- This message was sent by Atlassian JIRA (v6.3.4#6332)
