> Hi from France,
> Hope my english will be clear enough to explain what we encounter :D
> We use org.apache.pdfbox:preflight:3.0.6, calling static method PreflightParser.validate we encounter "Too many open files" issues.
> We solved it locally by extending PreflightParser, implementing Closeable interface and overriding validate function.
> Exemple of our solution :
> {code:java}
> public class CustomPreflightParser extends PreflightParser implements Closeable {
>   public static ValidationResult validate(File file) throws IOException {
>     ValidationResult result;
>     try(
>       // we move PreflightParser initialisation here
>       CustomPreflightParser parser = new CustomPreflightParser(file);
>       PreflightDocument document = (PreflightDocument) parser.parse()
>     ) {
>       result = document.validate();
>     }
>     catch (SyntaxValidationException e)
>     {
>       result = e.getResult();
>     }
>     return result;
>   }
>   @Override
>   public void close() {
>     IOUtils.closeQuietly( this.source );
>     IOUtils.closeQuietly( this.document );
>     // May be missing close ressources, seems to be enought for us
>   }
> }
> {code}
> We didn't spend more time on it so may be there is a better solution ?
> We wanted to share it with you in case you validate the issue and provide a proper fix.
> And may be it could help other to avoid having the same issue (or have a quick imperfect solution).
> Hope this could help :)
> Regards,
> Théo Lenoble
