Fontbox does not close file descriptor when loading fonts.

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:

Thoughts?

Thanks for PDFBox - it's been really helpful!
