GraalVM - New JIT Compiler and Polyglot Runtime for the JVM
GraalVM is based on an Oracle Labs JDK 8 with JVMCI support. For a default download, the bin directory contains the following language execution binaries: java, js, node, lli, native-image. With the gu installer tool, additional languages can be installed, including ruby, python, and R.
Performance - Graal incorporates our research on compiler technology, and offers better peak performance on some workloads than a traditional JVM.
Interoperability - Languages executed in Graal can call each other without overhead and libraries from other languages can be used.
Embeddability - Embed dynamic languages and native code with sandboxing capabilities.
Tooling - Graal benefits from JVM-based tooling and all languages share common tooling such as debugging and profiling.
