John Hewson commented on PDFBOX-1094:
-------------------------------------
Looks like this is an IOException which was being silently ignored previously.
It appears to be a parsing error, in the logs I get:
{code}
Dec 31, 2014 3:52:15 PM org.apache.pdfbox.pdfparser.NonSequentialPDFParser
checkXrefOffsets
SEVERE: Can't find the object 2 65536 (origin offset 0)
Dec 31, 2014 3:52:15 PM org.apache.pdfbox.pdfparser.BaseParser parseCOSArray
WARNING: Corrupt object reference at offset 226791
Dec 31, 2014 3:52:15 PM org.apache.pdfbox.pdfparser.BaseParser
parseCOSDictionary
WARNING: Invalid dictionary, found: 'e' but expected: '/'
Dec 31, 2014 3:52:17 PM
org.apache.pdfbox.pdmodel.graphics.shading.AxialShadingPaint createContext
{code}
Which is triggered by shading Sh18. The exceptions is thrown in relation to
object [189 0] which is the 3rd element in the array of functions an according
to AR's preflight should look like this:
!preflight.png!
However, we're parsing object [189 0] as:
{code}
COSName{Function}" -> "COSObject{190, 0}"
"COSName{Coords}" -> "COSArray{[COSInt{0}, COSInt{0}, COSInt{1}, COSInt{0}]}"
"COSName{BBox}" -> "COSArray{[COSFloat{-0.000015259}, COSFloat{-0.250916},
COSFloat{0.}]}
{code}
Which appears to be from object [181 0]... it's not the right object at all.
P.S. The NPE is a separate bug in the error handling which I'll fix.
