public void addFont(File fontFile, final String fontFamilyNameOverride, final Integer fontWeightOverride,
final IdentValue fontStyleOverride, final boolean subset) throws IOException {
/
* Specialcase for TrueTypeCollections
*/
if (fontFile.getName().toLowerCase(Locale.US).endsWith(".ttc")) {
//one
addFontCollection(fontFile, fontFamilyNameOverride, fontWeightOverride, fontStyleOverride, subset);
return;
}

	/*

I got the same problem and made a pullrequest with a fix #215

If you need a workaround, you can just use a FSSupplier to provide the font as InputStream. The bug only happens with font files.
