Subversion 1.9.7-4ubuntu1 and 1.9.12 fail to build on Ubuntu 18.04 because they use javah, that was removed in OpenJDK 10 (the default-jre-headless package installs OpenJDK 11), and there is no equivalent of the -force flag in its replacement (javac). Therefore, I am packaging the latest version of the next Subversion LTS (1.10.8) based on the packaging in Debian buster.
