I ran into this and have modified the Dockerfile to try OpenJDK instead since Oracle appears to have made use of their Java too annoying to mess with. Partial changes:

add-apt-repository ppa:openjdk-r/ppa &&
apt-get update &&
apt-get install -y openjdk-8-jre

Define commonly used JAVA_HOME variable

ENV JAVA_HOME /usr/lib/jvm/default-java

I don't know yet whether that is entirely effective; I'm running into problems a bit later getting the Ruby gem stuff going.

I checked for whether any of the forks of this repo had more recent changes, and thus some idea that they might have successfully built for someone recently, but they are all several years old. Bit rot is a thing.
