Acrobat will display most (but not all) annotations without an /AP (appearance stream) entry, but other pdf renderers will not. To get the annotation to display in anything other than acrobat, you actually have to issue the draw (postscript) commands into the appearance stream (i.e. move to position, draw line, draw text, et cetera). It sounds like it should be easy, but the reverse-engineering is horribly time consuming and imprecise. It's easier to just specify "use acrobat"

The result I am looking for is that the PDFBox app's PDFReader function be able to display the PDF file created by the Annotation.java example provided in the PDFBox examples. A fix to either one would likely lead to a solution to the more project-specific problems I am having. Thanks!
