> 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
> Assignee: Tilman Hausherr
> Priority: Minor
> Labels: file_leak
> Fix For: 2.0.12, 3.0.0 PDFBox

> My app has been getting "java.io.FileNotFoundException (No file descriptors
> available)" and I've confirmed that 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 tried performing this in a lazy initialization, but it blew up:
> java.lang.RuntimeException: java.io.IOException: The TrueType font null does
> not contain a 'cmap' tableCaused by: java.io.IOException: The TrueType font
> null does not contain a 'cmap' table
