GraalVM

assess?

GraalVM is a universal virtual machine by Oracle for running applications written in JVM languages, JavaScript, Python, Ruby and R, as well as C/C++ and other LLVM-based languages. At its simplest, GraalVM can be used as a more performant VM for JVM and other supported non-JVM languages. But it also allows us to write polyglot applications with very little performance impact; and its Native Image utility (currently only available as an Early Adopter Technology) lets us compile Java code ahead of time to stand-alone executables for faster startup and less memory use. GraalVM has generated a lot of excitement in the Java community, and a host of Java frameworks (including Micronaut, Quarkus, and Helidon) are already taking advantage of it.
