I think it's the caucaine "image" in this PDF which is really a lot of tiny
images. The exception log is an anomaly, nothing more, here's some details:
Warning [PDImageXObject] image : BufferedImage@1e52ee34: type = 1
DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0
IntegerInterleavedRaster: width = 3 height = 4 #Bands = 3 xOff = 0 yOff = 0
dataOffset[0] 0
Warning [PDImageXObject] image2: BufferedImage@4e6ae9ad: type = 10
ColorModel: #pixelBits = 8 numComponents = 1 color space =
java.awt.color.ICC_ColorSpace@131f2861 transparency = 1 has alpha = false
isAlphaPre = false ByteInterleavedRaster: width = 4 height = 4 #numDataElements
1 dataOff[0] = 0
Warning [PDImageXObject] af : AffineTransform[[1.333333333333333, 0.0,
0.0], [0.0, 1.0, 0.0]]
According to the profiler, most time is lost in PDICCBased.loadICCProfile() and
then in {{new ComponentColorModel}} (which is done only to catch future
exceptions). 1/4 of it is lost in {{ICC_COlorSpace.toRGB()}}.
