Antoni Mylka commented on PDFBOX-1227:
--------------------------------------

The PDF is obviously from PDFBOX-706, not PDFBOX-708. My test (as uploaded, with default maven-surefire-plugin settings i.e. -Xmx now results in:

java.lang.OutOfMemoryError: Java heap space

	at org.apache.pdfbox.io.RandomAccessBuffer.write(RandomAccessBuffer.java:131)

Now when I increase the heap size (by binary search, needs at least -Xmx296m), the pictures 51,52,53 get extracted properly. They aren't black any more, so there must have been some improvement in this respect. BUT now more pictures are found. I comment out those 'ifs' in that code, so that all pictures are supposed to be non-black. Then my test extracts 53 pictures and dies with this at picture 54

java.lang.ArrayIndexOutOfBoundsException: Coordinate out of bounds!
	at sun.awt.image.ByteInterleavedRaster.getDataElements(ByteInterleavedRaster.java:301)
	at java.awt.image.BufferedImage.getRGB(BufferedImage.java:871)
	at org.apache.pdfbox.antoni.pub.TestPdfbox706FlexEnableBeta1.testFile2(TestPdfbox706FlexEnableBeta1.java:45)
	
So now it seems there are two problems: increased memory consumption and an array index exception. Three pictures are extracted properly now though.
