3288 csv file empty headers

[igorbeslic]

Ivica I added CSV sample which fails.
Added test tests number of detected columns - it fails probably because either our wrong configuration or issue in apache library

Header line which cant be processed
Header 1;Header 2;Header 3;;Header 5;;Header 7

Apache parser interprets first ;; as empty header, but it swalows second ;; which causes problem in later output processing

We can check this together before I fix it. (My plan is to provide own parser for header if apache csv fails on this)

1. Expose convert utils with contex.. (see ContextImpl -> fileBlock)
2. Try newer version of jackson csv
3. If newer version of jackson csv has same issue with headers, implement own header reader

@karlocehulic19 let's connect to give you guidelines for this one. It has failing integration test which should PASS once implementation properly process sample CSV file.

@ivicac apache csv requires:
compileOnly group: "org.apache.commons", name: "commons-collections4", version: "4.4" compileOnly group: "org.apache.commons", name: "commons-compress", version: "1.26.0" compileOnly group: "org.apache.commons", name: "commons-csv", version: "1.9.0"

I know that for jackson libs we relie to Spring BOM defined versions

What would be th case for apache??

Btw. according to the plan:

• @karlocehulic19 would inspect apache impl
• If not OK, he will do our own implementation
