Remember that JIT allows for runtime analysis in addition to static analysis, which can allow for better performance, particularly on long-running applications. There are lots of classes and modules that perform better when managed with the JIT instead of AOT. It is still necessary for the JIT compiler.The JVM still provides a number of things people tend to want: The only exceptions would be Java classes compiled to machine code with jaotc and then linked together with the appropriate modules.īut shipping multiple releases containing runtimes for specific platforms makes me wonder why not just compile native code in the first place? I'll also point out that when you do the whole jlink thing, what you're going to get is a minimal JVM in machine code (the parts you'd have previously directed them for a download to) and then it's going to load the JAR, which is just dumped into the executable as reference data. However, outside of server situations, this is probably not what you want to do. Adopt OpenJDK actually has a download for just the runtime, if you're involved in a situation where it makes sense (there are some things in enterprise environments that become much nicer if you separate out the runtime with the environment). has always been the idea to write code once and run it on all platforms (because users already installed a specific JRE once). Wouldn't that make Java platform dependent again? A big distinguisher between JVM based and native languages like C, C++.
