Gary Gregory commented on CSV-197:
----------------------------------
The parser implements close() which calls close() on the lexer which closes()
the reader.
So all you have to do is manage the parser in a try-with-resources block:
{code:java}
try (final CSVParser parser = CSVParser.parse(...)) {
...
}
{code}
> CSVParser doesn't close the underlying handle after iteration

> Key: CSV-197
> URL: https://issues.apache.org/jira/browse/CSV-197
> Project: Commons CSV
> Issue Type: Bug
> Components: Parser
> Reporter: Prateek Rungta
> Priority: Minor
> Fix For: Patch Needed, Discussion, 1.4.1
>
>
> The following code leaks file handles:
> {code}
> CSVParser parser = // setup parser
> for (CSVRecord rec: parser) {
> }
> // leak
> {code}
> I'd expect the underlying iterator to close() if it's finished iterating.
