@diegomarquezp We're likely seeing this failure because docker hub removed the openjdk-8-jre-slim image (deprecation notice). https://hub.docker.com/_/eclipse-temurin is listed as an alternative so we can use that as a replacement for now.

Stacktrace from kokoro-ubuntu:

Thanks @mpeddada1, yes I noticed the deprecation. I changed it to eclipse-temurin.
