Tilman Hausherr resolved PDFBOX-2214.
-------------------------------------

       Resolution: Fixed
    Fix Version/s: 2.0.0
                   1.8.7
         Assignee: Tilman Hausherr

The graphics stack must have at least one element because of peek() in PDFStreamEngine, so I changed the previous change to "> 1" instead of "> 0". I also modified the log that it is an error and not just a debug, because it happens with a broken PDF. Done in rev 1612360 for the trunk and rev 1612363 for the 1.8 branch. The rendered image is now better than Adobe Reader.
