> I get this exception with the attached file:

> java.lang.ClassCastException: org.apache.pdfbox.cos.COSName cannot be cast to

> {code}
> The cause is this:
> {code}
> 28 0 obj
> [
> /Separation /PANTONE#20723 /DeviceGray /Identity

> endobj
> {code}
> Although the identity function isn't in the spec for the separation
> colorspace, it is mentioned elsewhere (TransferFunction) so we need it anyway.
