> Exception in thread "main" java.lang.NullPointerException

> 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.
