Glen Peterson updated PDFBOX-4242:
----------------------------------
Priority: Major (was: Minor)
> Fontbox does not close file descriptor when loading fonts.
> ----------------------------------------------------------
>
> Key: PDFBOX-4242
> URL: https://issues.apache.org/jira/browse/PDFBOX-4242
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.9
> Reporter: Glen Peterson
> Priority: Major
> Labels: file_leak
>
> My app has been getting "java.io.FileNotFoundException (No file descriptors
> available)" and I think it's because fontbox isn't closing it's file
> descriptors.
> In org.apache.fontbox.ttf.TTFParser there's this method:
> {{public TrueTypeFont parse(File ttfFile) throws IOException {}}
> {{ RAFDataStream raf = new RAFDataStream(ttfFile, "r");}}
> {{ try {}}
> {{ return this.parse((TTFDataStream)raf);}}
> {{ } catch (IOException var4) {}}
> {{ // close only on error (file is still being accessed later)}}
> {{ raf.close();}}
> {{ throw var4;}}
> {{}}}
> {{}}}
> I would have expected to see the close() in a finally block so that the file
> is always closed, not just on exceptions. Presumably, you can keep it in
> memory without leaving the file descriptor open?
> {{public TrueTypeFont parse(File ttfFile) throws IOException {}}
> {{ RAFDataStream raf = new RAFDataStream(ttfFile, "r");}}
> {{ try {}}
> {{ return this.parse((TTFDataStream)raf);}}
> {{ } catch (IOException var4) {}}{{ raf.close();}}
> {{ throw var4;}}
> {{ } finally {}}
> {{ raf.close();}}
> {{}}}
> {{}}}
> I can perform this in a lazy initialization, so if there's still good reason
> to leave the file descriptor open, I can at least only leave it open once
> instead of every time someone requests a PDF! But maybe the file descriptor
> doesn't need to be left open, and you can just close it?
> Thanks for PDFBox - it's been really helpful!
