Tilman Hausherr commented on PDFBOX-5375:
-----------------------------------------

I'm not convinced by this; IMHO the current attitude in software development is 
that failures should be handled with exceptions, not with return codes. There 
are a few cases were we don't respect this rule (e.g. broken fonts), we 
shouldn't add more. Why don't you add the decoder? Is this SO question from you 
/ is this from somebody in your team?

If you don't trust the library, the source code of the JPEG2000 decoder is 
available:

>             Project: PDFBox
>          Issue Type: Bug
>          Components: PDModel
>    Affects Versions: 2.0.25, 3.0.0 PDFBox
>            Reporter: Thomas Ledoux
>            Priority: Major
>         Attachments: patch.txt, patch2.txt

> Currently, when a PDF embeds JPEG2000 images, the simple parsing of the file 
> generates a warning
> when the code hits a call to getXObject(name) from a PDResources for a image 
> without creating the
> underlining PDFXObjectImage object, related to the absence of the JAI 
> third-party.
> However, when we just want to access the width or height propertis (which are 
> defined outside the stream in the associated dictionnary).
> Looking at the constructor of PDFXObjectImage, it appears that the image is 
> always read to retrieve the colorspace.
> The proposed patch is moved this initialization to the getColorSpace() method 
> so that the object is created and the Exception will be raised only if the 
> image needs to be really accessed.
