------------------------------------------------------------------
I ran another test with the digitalcorpora set of 250000 pdfs and there were no
unchecked exceptions. My suggestion is what we mention twelvemonkeys on
https://pdfbox.apache.org/2.0/dependencies.html as an optional dependency. The
following text could be included below the text "To write TIFF images a JAI
ImageIO Core library will be needed":
{quote}
For better support of embedded JPEG files in PDFBox 2.0, use TwelveMonkeys
ImageIO https://github.com/haraldk/TwelveMonkeys , version 3.1.0 or higher.
{code}
<dependency>
<groupId>com.twelvemonkeys.imageio</groupId>
<artifactId>imageio-jpeg</artifactId>
<version>3.1.0</version>
</dependency>
{code}
Note that JDK 1.7 is required for twelvemonkeys, while PDFBox 2.0 requires only
JDK 1.6.

> While working on PDFBOX-2128 I decided to try twelvemonkeys for JPEG reading
> and the first impression is excellent. It seems that the author is making a
> big effort in handling even the most broken JPEG files (similar to what we do
> with PDFs). This issue is to collect problem files and discuss all
> experiences and decide whether we should bundle twelvemonkeys with PDFBox or
> rather just recommend it as an optional solution.
