Bug Description

pdfannotextractor is a script that is part of the pax package that is part of texlive-latex-extra : https://packages.ubuntu.com/focal/texlive-latex-extra

The default installation throws this error:

$ pdfannotextractor --debug submission.pdf

The problem is that the classpath is not properly configured to use the jar. Simply adding the "-jar" flag solves the problem:

$ java -jar /usr/share/texlive/texmf-dist/scripts/pax/pax.jar submission.pdf
* Processing file `submission.pdf' ...

In the code, pdfannotextractor.pl, the change would be located here:

sub launch_pax () {
    check_prg $prg_java, 1;
    my @cmd = ($prg_java);
    push @cmd, $path_jar_pax;
    push @cmd, @ARGV;
    debug 'System', "@cmd";

Thanks for the link. Recent problems with pax seem to revolve around pdfbox; however, the current packaging includes pdfbox, possibly to avoid those problems.

Here is a patch that fixes the bug under discussion:
