Excelsior JET is a proprietary Java SE technology implementation built around an ahead-of-time (AOT) Java to native code compiler. The compiler transforms the portable Java bytecode into optimized executables for the desired hardware and operating system (OS). Also included are a Java runtime featuring a just-in-time (JIT) compiler for handling classes that were not precompiled for whatever reason (e.g. third-party plugins or dynamic proxies), the complete Java SE API implementation licensed[1] from Oracle, and a toolkit to aid deployment of the optimized applications.

Overview

Excelsior JET has passed the "official" test suite (TCK) for Java SE 7, and is certified Java Compatible on a number of Windows and Linux variations running on Intel x86, AMD64/Intel 64 and compatible hardware.

The Enterprise Edition supports the Equinox OSGi runtime at the JVM level, enabling ahead-of-time compilation of Eclipse RCP (Rich Client Platform) applications,[2][3] and version 7.0 added such support for Web applications running on Apache Tomcat.[4][5]

Excelsior JET Embedded[6] implements the Java SE for Embedded technology in a very similar manner, the only major differences are in licensing and pricing.
