Tadhg Pearson created CSV-198:
---------------------------------

             Summary: Cannot parse file by header with custom delimiter on Java 1.6
                 Key: CSV-198
                 URL: https://issues.apache.org/jira/browse/CSV-198
             Project: Commons CSV
          Issue Type: Bug
          Components: Parser
    Affects Versions: 1.4
         Environment: Java 1.6, Windows
            Reporter: Tadhg Pearson


Reading a CSV file from the parser using the header line results in "IllegalArgumentException: Mappng for <column> not found" - even when the column exists in the file. In this case, we are using Java 1.6 and the file uses the ^ symbol to delimit columns. This works correctly in Java 7 & Java 8.

The code required to reproduce the issue is below. You can find the optd_por_public.csv file referenced at https://raw.githubusercontent.com/opentraveldata/opentraveldata/master/opentraveldata/optd_por_public.csv

It will need to be on the classpath to run the unit test.  Hope that helps, Tadhg

You should get the following output

--------------------------------------
java.lang.IllegalArgumentException: Mapping for location_type not found, expected one of [iata_code,icao_code,faa_code,is_geonames,geoname_id,envelope_id,name,asciiname,latitude,longitude,fclass,fcode,page_rank,date_from,date_until,comment,country_code,cc2,country_name,continent_name,adm1_code,adm1_name_utf,adm1_name_ascii,adm2_code,adm2_name_utf,adm2_name_ascii,adm3_code,adm4_code,population,elevation,gtopo30,timezone,gmt_offset,dst_offset,raw_offset,moddate,city_code_list,city_name_list,city_detail_list,tvl_por_list,state_code,location_type,wiki_link,alt_name_section,wac,wac_name]
