--- Comment #3 from Peter Hull peterhull90@gmail.com --- Further information: this doesn't occur on Debian 9. They have an older version of ant (1.9.9) and put all jars into /usr/share/java rather than the way they are organised on Fedora. I wasn't able to check if Debian or Fedora apply any patches to the stock Apache Ant that may be relevant.
