Bug#928813: libapache2-mod-jk: Jk can not find any configured worker

[McIntyre, Vincent (CASS, Marsfield)]

Package: libapache2-mod-jk
Version: 1:1.2.46-1
Tags: patch
Followup-For: Bug #928813

I am seeing this too. I worked around like this

    # cd /etc/apache2/mods-available
    # ln -s httpd-jk.conf jk.conf
    # a2enmod jk
    Enabling config file jk.conf.
    To activate the new configuration, you need to run:
      systemctl restart apache2
    # systemctl restart apache2
    # echo $?
    0

If there really is a need to maintain the discordant file naming
(which I also think is silly) then either the package needs this change
