[jira] [Closed] (PDFBOX-3086) OutOfMemory while building font cache
caused by "PingFang" font (Mac OS X El Capitan)

Tilman Hausherr closed PDFBOX-3086.
-----------------------------------
Resolution: Duplicate
Closing as duplicate of PDFBOX-3082, I've added you as watcher there. Until being disproven, I'm attributing the difference in severity to different types of fonts. But the basic problem is the same, i.e. incredible memory usage. Hopefully this will be fixed as part of the font cache rework.

> Key: PDFBOX-3086
> URL: https://issues.apache.org/jira/browse/PDFBOX-3086
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.0
> Environment: Mac OS X El Capitan
> Reporter: Florian Polter
>
> We're facing a OutOfMemory error while building the font cache. This happens for the font file "PingFang" which is a new system font for Mac OS X El Capitan (http://appleinsider.com/articles/15/06/08/apple-targets-china-japan-with-new-os-x-el-capitan-system-fonts-and-input).
> The font file seems to be very large (about 65.5m). We tried to adjust our vm options (with -Xmx8096m for example) but had no chance to build the project.
> As the "PingFang" font is a system font there is no (supported) chance to remove the font from the system.
> Here you'll see the output from the test:
> {code:borderStyle=solid}

> Made a test by updating the checkFontfile method in FontFileFinder.java to ignore the "PingFang" font and it works.

> private boolean checkFontfile(File file)
> {
> String name = file.getName().toLowerCase();
> return (name.endsWith(".ttf") || name.endsWith(".otf") || name.endsWith(".pfb") || name.endsWith(".ttc") && !name.startsWith("pingfang"));
> }
> {code}
> Of course this isn't a nice solution but i've no idea how to resolve the issue as i'm not aware of the PDFBox development. Maybe someone else has a clean solution for this problem.
