             Summary: False negative on PDF/A-1A with wrongly given causes " Invalid graphics object, DestOutputProfile isn't a valid ICCProfile: Invalid ICC Profile Data" and "Invalid Color space, The operator "rg" can't be used with CMYK Profile"
                 Key: PDFBOX-3136
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3136
             Project: PDFBox
          Issue Type: Bug
          Components: Preflight
            Reporter: Antoine Ribes


Using the code of the CookBook for PDF/A validation (given for 1.8.10) :
- with the test_little-A1a.pdf file (Adobe preflight (and pdfbox:1.8.10) tells me it's a valid PDF/A-1A)
- and only replacing the code "parser.parse()" with "parser.parse(Format.PDF_A1A)",

result.isValid() is false with version 2.0.0-RC2. Displayed results errors are :
- 2.1.4 - Invalid graphics object, DestOutputProfile isn't a valid ICCProfile: Invalid ICC Profile Data
- 2.1.4 - Invalid graphics object, DestOutputProfile isn't a valid ICCProfile. Caused by : Invalid ICC Profile Data
- 2.4.1 - Invalid Color space, The operator "rg" can't be used with CMYK Profile

Some log is displayed :
WARN [org.apache.pdfbox.filter.FlateFilter] - FlateFilter: premature end of stream due to a DataFormatException
DEBUG [org.apache.pdfbox.io.ScratchFileBuffer] - ScratchFileBuffer not closed!
WARN [org.apache.pdfbox.filter.FlateFilter] - FlateFilter: premature end of stream due to a DataFormatException



Note : Running same code with the pdfbox and preflight version 2.0.0-RC1 on the same file, I get the exception :
org.apache.pdfbox.preflight.exception.ValidationException: Unable to parse the ICC Profile.

And a similar result as with 2.0.0-RC2 is obtained with 1.8.8.
