Description

This was originally stumbled upon when running a 69-page long PDF through Tika. I could isolate the issue to in-between those two pages. Tika ends up responding with a faulty XML, as the attached screenshot shows - together with a stacktrace on the logs that includes the PDFBox exception, shown below as reproduced from the standalone CLI tool.

I'm using Tika 1.1.4, although I'm not exactly sure what version of PDFBox it uses. Here's the base Dockerfile.
