It does so by pre-analysing what a particular Java application needs (starting from a provided main class), pre-compiling and including only code that is really needed. You can even write your own language and leverage GraalVM’s interpreter!įinally, GraalVM offers the possibility to build native images of Java applications, which have nearly instant startup time and consume less memory. Data can be shared, and code cross-executed. Moreover, GraalVM offers the possibility of running Java code alongside R, Python, Javascript and Ruby, by providing a common, sandboxed runtime. The original JIT can still be used, if needed (which is useful for benchmarking), by providing the -XX:+UseJVMCICompiler option. That means you won’t get the newest Java features however, the main focus of GraalVM is on other languages, such as Scala and Kotlin, so this should not be a blocker. GraalVM distribution is based on Java 8 (OpenJDK 1.8.0_212 to be precise).

Apart from the JIT, the other parts of the JVM remain the same.
