Next time please add the stack trace, which is:
{code}
Exception in thread "main" java.lang.IllegalArgumentException: Numbers of source Raster bands and source color space components do not match
at java.awt.image.ColorConvertOp.filter(ColorConvertOp.java:482)
at com.sun.imageio.plugins.jpeg.JPEGImageReader.acceptPixels(JPEGImageReader.java:1280)
at com.sun.imageio.plugins.jpeg.JPEGImageReader.readImage(Native Method)
at com.sun.imageio.plugins.jpeg.JPEGImageReader.readInternal(JPEGImageReader.java:1247)

at org.apache.pdfbox.filter.DCTFilter.decode(DCTFilter.java:91)
{code}
This is a java bug. You can catch it like every other exception if you want.
You can avoid it by using the [twelvemonkeys library|https://github.com/haraldk/TwelveMonkeys]. See also PDFBOX-4221 and PDFBOX-4258.

> Key: PDFBOX-5036
> URL: https://issues.apache.org/jira/browse/PDFBOX-5036
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.21
> Environment: JDK11
> Reporter: Andreas Gerstinger
> Priority: Major
> Attachments: Phaeton.pdf
>
>
> An IllegalArgumentException (runtime exception) is thrown in the getImage() method of PDImageXObject. The method declares to throw IOException, which is fine, but I do not know how to prevent it to throw the IllegalArgumentException. Only happens for some PDFs, one that is affected is attached.
> Here is the code that provokes the exception:
> {noformat}
> public static void main(String[] args) {
> try {
> PDDocument document = PDDocument.load(new File("Phaeton.pdf")); // see attachment for an affected file
> PDResources pdRes = document.getPages().get(0).getResources();
> for (COSName name : pdRes.getXObjectNames()) {
> PDXObject o = pdRes.getXObject(name);
> if (o instanceof PDImageXObject) {
> PDImageXObject img = (PDImageXObject) o;
> img.getImage(); // This throws an java.lang.IllegalArgumentException (runtime exception) - bug in PDFBOX???
> }
> }
> } catch(IOException e) {
> System.out.println("IOException thrown..."); // do something here
> }
> }
> {noformat}
