Minor Description
This class appears to only be used in the test for itself. It's also easily confused with org.apache.solr.response.CSVWriter
I propose we remove this class entirely. Is there any reason to believe from it's past history (of which I know nothing) that it might be depended upon by outside code and require a deprecation cycle?
Presently it contains a System.out.println and a eclipse generated catch block that precommit won't like if we enable checking for System.out.println, which is why this ticket is a sub-task. If we do need to deprecate it then I propose we remove the print and simply re-throw the exception as a RuntimeException
