> I'm trying to read annotations from PDFs and am having trouble matching up
> replies with the annotations they're in reply to.
> PDPage.getAnnotations() returns a list of PDAnnotation. When I have
> a PDAnnotationMarkup, I try to call getInReplyTo to get the previous
> annotation in the thread. But I have two problems:
> 1) getInReplyTo() crashes if the annotation isn't a reply. It'd be nice if
> it just returned null. I can work around this by getting the COSDictionary
> and checking for an IRT entry first.
> (... other problem already solved...)

> it is an IOException, this isn't as bad as a nullpointerexception. But it is kindof weird indeed, usually we just return null when something doesn't exist.
