Our current container java 8 container is 262 MiBs and layers on top of openjdk:8-bullseye which is 226 MiBs compressed while eclipse-temurin:8 is 92 MiBs compressed and eclipse-temurin:8-alpine is 65 MiBs compressed.
I would rather not get into issues with C library differences caused by the alpine project so I would stick with the safer option and let users choose alpine when building their custom container if they feel it provides a large win for them. We can always swap to alpine in the future as well if the C library differences become a non-issue. So swapping to eclipse-temurin will save us a bunch on the container size which should help with container transfer and hopefully for startup times as well.
