+In this example, Java backends won't be compiled.

+On Debian-like systems (which includes ubuntu), you need the following
+packages: sun-java6-jdk libgcj10-dev. If you cannot find the
+libgcj10-dev, try another version, like libgcj9-dev (on Ubuntu before
+9.10) or libgcj11-dev (not released yet, but certainly one day).
+Please note that you need to activate the contrib and non-free
+repositories in Debian, and the universe ones in Ubuntu. Java comes at
+this price...
