The GraalVM compiler, Graal, was started by manually converting the code of the HotSpot client compiler (named "C1") into Java, replacing the previous Maxine compiler. [ 9 ] Graal was included in HotSpot-based JDK releases such as OpenJDK from Java SE 9 through 15, to provide experimental ahead-of-time compilation.
Jython includes almost all of the modules in the standard Python programming language distribution, lacking only some of the modules implemented originally in C. For example, a user interface in Jython could be written with Swing, AWT or SWT. Jython compiles Python source code to Java bytecode (an intermediate language) either on demand or ...
Sun released most of its Java source code as free software in May 2007, so it can now almost be considered a free Java implementation. [1] Java implementations include compilers, runtimes, class libraries, etc. Advocates of free and open source software refer to free or open source Java virtual machine software as free runtimes or free Java ...

The ROSE compiler framework, developed at Lawrence Livermore National Laboratory (LLNL), is an open-source software compiler infrastructure to generate source-to-source analyzers and translators for multiple source languages including C (C89, C99, Unified Parallel C (UPC)), C++ (C++98, C++11), Fortran (77, 95, 2003), OpenMP, Java, Python, and PHP.
The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK.
Following their promise to release a Java Development Kit (JDK) based almost completely on free and open-source code in the first half of 2007, [11] Sun released the complete source code of the Java Class Library under the GPL on May 8, 2007, except for some limited parts that had been licensed to Sun by third parties and Sun was unable to re-license under the GPL.
