Description

From Floris in the user mailing list:

I am trying to define a Separation color space but get the following error message if I try to run the program posted beneath. The error seems to be quite local; coming only from the setAlternateColorSpace. What is going on here? I am using org.apache.pdfbox:pdfbox:app-1.8.10-20150327.210556-4 (in this version DeviceN is working) and java version 1.8.0_40-ea.

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 2, Size: 2

    at org.apache.pdfbox.cos.COSArray.set(COSArray.java:148)

    at com.here.devicentest.DeviceNTest.main(DeviceNTest.java:43) 

The cause is this initialisation:

public PDSeparation()
    {
        array = new COSArray();
        array.add( COSName.SEPARATION );
        array.add( COSName.getPDFName( "" ) );
    }

However the separation colorspace has 4 elements.
