Summary: PreflightParser .validate leads to "Too many open files"
Key: PDFBOX-6120
URL: https://issues.apache.org/jira/browse/PDFBOX-6120
Project: PDFBox
Issue Type: Bug
Components: Preflight
Affects Versions: 3.0.6 PDFBox
Reporter: Théo Lenoble
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 :
```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
}
}
```
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
