Michael McCandless commented on SOLR-3296:
------------------------------------------
bq. wrt commons-csv alternatives, it's too risky for little/no gain.
This confuses me: commons-csv is unreleased, while there are other
license-friendly packages (eg opencsv) that have been released for
some time (multiple releases), been tested in the field, had bugs
found & fixed, etc.
Why use an unreleased package when released alternatives are
available?
bq. I put a lot of effort into getting commons-csv up to snuff,
Wait: a lot of effort doing what? Did you have to modify commons-csv
sources? Or do you mean open issues w/ the commons devs to fix
things/add test cases to commons-csv sources (great!)...?
bq. Switching implementations would most likely result in a lot of regressions
that we don't have tests for.
I'd expect the reverse, ie, it's more likely there are bugs in
commons-csv (it's not released and thus not heavily tested) than eg
in opencsv.
And if somehow that's really the case (eg we have particular/unusual
CSV parsing requirements), we should have our own tests asserting so?

> OpenCSV uses ASL2.
