Today, the container image no longer builds. Discovered on develop but master is affected too.
Build of the image fails because ddist() function downloads the wrong thing - a HTML page instead of gzip archive with Tomcat.
Image build fails when gzip tries to unpack html page.

The ddist function tries to contact https://www.apache.org/dyn/closer.cgi?action=download&filename=tomcat/tomcat-9/v9.0.41/bin/apache-tomcat-9.0.41.tar.gz which should properly determine a mirror.
However, the mirror it redirects us to is return as https://..../apache/ and not a concrete file to download as it was before.
Wget then downloads the html page instead of a gzip. Because the check in the function is if [ -s ... ] (file of non-zero lenght determines success), the download is "successful" even if actually is not.

This seems to be a change in the CDN behavior.
Quick fix is to disable downloading from the CDN, because other mirrors work fine.
