I dug a little deeper and, instead of the characters between stream and 
endstream, PDFBox seems to think what I pasted below is a stream and tried to 
decompress it and that apparently is the cause of the exception:

 If I put a breakpoint at line 70 in FlateFilter.java ( int read = 
in.read(buf); ) and consume that input stream 'in' in a debugger, the image is 
rendered with no error and it even looked fine. (no discernible differences 
between the image and the PDF).
