Answer 1

For me the issue was regarding a bug in AdoptOpenJDK: https://github.com/AdoptOpenJDK/openjdk-build/issues/682

I fixed the issue by installing ttf-dejavu manually in my dockerfile

FROM adoptopenjdk/openjdk8:alpine-jre

# Workaround for wrong font configuration in adoptopenjdk
# https://github.com/AdoptOpenJDK/openjdk-build/issues/682
RUN apk update && apk upgrade \
   && apk add --no-cache ttf-dejavu \
   # Install windows fonts as well. Not required..
   && apk add --no-cache msttcorefonts-installer \
   && update-ms-fonts && fc-cache -f

AND by running the application with the flag -Djava.awt.headless=true
