I think the method org.apache.pdfbox.pdmodel.PDResources.getColorSpaces
(PDResources.java:311) did not return a object if their is no image color space
but the code line
org.apache.pdfbox.preflight.content.ContentStreamEngine.validImageColorSpace(ContentStreamEngine.java:323)
expects a object in any case.
