Do you know what's needed for this to pass?

[smlambert]

some related discussion that describes a workaround: AdoptOpenJDK/openjdk-docker#75 (and adoptium/temurin-build#693)

[sophia-guo]

This also happened to linux-x64 containers

[sxa]

Based on the other issues this will need the fontconfig package (which pulls in fonts-dejavu-core, fontconfig-config libfontconfig1` on Ubuntu) added to the DockerStatic containers.

[sxa]

fontconfig should now be available on all active docker static containers other than the Alpine ones (which are headless).
Please reopen if you see this anywhere again.
