Is this one going to be pointing anywhere useful? I'd be tempted to hold off a bit on these changes until we've verified they work properly. I get the impression the JDK11 in particular may be causing the hangs on the test jobs as some of the later versions don't seem to be freezing so much at the moment.

yeah, I switched the Zulu 7 build to be installed there for now

Just spotted this PR as not having been merged. I'm having a look at it and it looks like it's trying to symlink zulu into /usr/lib/jvm/jdk-xx, yet it removes the zulu downloads.

Also the - ansible_distribution != "Alpine" in the top level for the adoptopenjdk_install role seems to actively stop it trying to install the Temurin JDKs on Alpine. Am I missing something?

@gdams Will need a rebase
