The next step is to create a `--with-import-jvms=,[,...]`, so that it is possible to simulate a multi-JVM build by e.g. bash configure --with-jvm-variant=zero --with-conf-name=zero-hotspot make hotspot bash configure --with-jvm-variant=server --with-conf-name=combined --with-import-jvms=zero:./build/$PLATFORM/jdk/lib/zero or something like that. When that exists and is working, and all downstream users has had time to adapt, then we can remove multi-JVM build support (and boy am I longing for that day). If you want to help by implementing the `--with-import-jvms` options, you are more than welcome! - PR: https://git.openjdk.java.net/jdk/pull/5526

I have a vague recollection that ether @magicus or someone else at one point suggested eliminating multi-variant builds, maybe that should be the next step in build simplification. - PR: https://git.openjdk.java.net/jdk/pull/5526
