Excelsior JET is a now-defunct 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. Excelsior JET was developed by Excelsior LLC, headquartered in Novosibirsk, Russia.
