Some observations:

* /usr/share/texlive/texmf-dist/scripts/pax/pdfannotextractor.pl would
  download PDFBox-0.7.3.zip from Sourceforge. That's a quite old
  version (in Debian in oldoldstable).
* Looking at
  pdfbox/src/main/java/org/apache/pdfbox/cos/ICOSVisitor.java (in the
  PDFBox source), I guess that this class is called
  org.apache.pdfbox.cos (and not org.pdfbox.cos) by now.
  A diff in the git repo (upstream tags) shows the same. Pseudo-diff:

diff --git a/current/src/org/pdfbox/cos/ICOSVisitor.java b/current/src/org/pdfbox/cos/ICOSVisitor.java
deleted file mode 100644
index 04b7542..0000000
--- a/current/src/org/pdfbox/cos/ICOSVisitor.java
+++ /dev/null

-package org.pdfbox.cos;
-public interface ICOSVisitor

diff --git a/pdfbox/src/main/java/org/apache/pdfbox/cos/ICOSVisitor.java b/pdfbox/src/main/java/org/apache/pdfbox/cos/ICOSVisitor.java
new file mode 100644
index 0000000..1a09c38
--- /dev/null
+++ b/pdfbox/src/main/java/org/apache/pdfbox/cos/ICOSVisitor.java

+package org.apache.pdfbox.cos;
+public interface ICOSVisitor


My conclusion is that /usr/share/texlive/texmf-dist/scripts/pax/pax.jar
(in texlive-latex-extra) needs to be adjusted to a "recent" version of PDFBox.

Reassigning the bug.


As a workaround it might work to
- download the old PDFBox zip, put the .jar in some directory and
- run the script as
  CLASSPATH=/path/to/PDFBox-0.7.3.jar /usr/share/texlive/texmf-dist/scripts/pax/pdfannotextractor.pl capturing-ddl.pdf
(or something similar)


Cheers,
