On x86_64 this is done by fetching and installing https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz <https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz>;, linked from https://jdk.java.net/archive/ <https://jdk.java.net/archive/>;.

We provide JDK 11 aarch64 vanilla OpenJDK builds here:
https://adoptopenjdk.net/upstream.html?variant=openjdk11&ga=ga

That's the closest equivalent (for OpenJDK 11u) to what Oracle does
with jdk.java.net for more recent JDKs.

Unfortunately, there are no vanilla OpenJDK 8u binaries for Aarch64 as
the port landed in mainline JDK with the release of JDK 9. So any
downstream builders would have to build from the aarch64-port 8u tree.
There are a variety of downstream builds of OpenJDK 8u aarch64 which
would suit your needs. For example the ones from AdoptOpenJDK (or
Eclipse Adoptium) here:
https://adoptopenjdk.net/releases.html?variant=openjdk8&jvmVariant=hotspot

Note the two links are not the same. The former are upstream builds,
the latter is a downstream curation of OpenJDK. Depending on what you
need both might work.

HTH,
