=== Deprecations

[[adoptopenjdk_download]]
==== AdoptOpenJDK toolchain download

Following the move from AdoptOpenJDK to Adoptium, under the Eclipse foundation, it is no longer possible to download an AdoptOpenJDK build from their end point.
Instead, an Eclipse Temurin or IBM Semeru build is returned.
