AOT implementation in the JDK, that we call the "HotSpot AOT" implements tiered compilation (look for $JAVA_HOME/bin/jaotc). It is also based on Graal, but with a different set of plugins. You get reasonably good startup and re-JITing afterwards. Of course it doesn't give you compactness on the SVM, but it supports regular java code with class loading, reflection, etc.
