	GNU Compiler for Java - Wikipedia, the free encyclopedia
		The GNU Compiler for Java (GCJ) is a free software compiler for the Java programming language that is part of the GNU Compiler Collection.
		It can compile Java source code to either Java Virtual Machine bytecode, or directly to machine code for any of a number of CPU architectures.
		The Compiled Native Interface (CNI) is a software framework for the GCJ which allows Java code to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in C++.

	Java bytecode - Wikipedia, the free encyclopedia
		It is possible to write Java bytecode in hand, however this method is never used in real life because nowadays the compilers are able to compile well performing code and no person is able to comprehend a piece of Java bytecode of considerable size.
		Gnu Compiler for Java, GCJ, compiles from the Java programming language to Java bytecode, is also able to compile to native machine code.
		If executing Java bytecode in a Java virtual machine is not desirable, a developer can also compile Java source code or Java bytecode directly to native machine code with tools such as the GNU Compiler for Java.

	Java - GPWiki
		Java's most important property is that programs are byte-compiled to a platform-independent format, which makes cross-platform programming very easy.
		These compilers allow you to create an executable program from the java source (not in bytecode), making the program faster on execution, but not portable when compiled.
		A such compiler is the GNU Compiler for Java, part of the GNU Compiler Collection.

		The GNU Compiler for Java (GCJ), a free software implementation of Java, has been in development for seven years, but with the Free Software Foundation's recent call for volunteers, the project is suddenly receiving more attention than ever before.
		For many, GCJ is seen as a means of ensuring that the next version of OpenOffice.org does not require non-free versions of Java for full functionality.
		Part of the larger GNU Compiler Collection (GCC), GCJ consists of three parts: gcj, a compiler that converts Java code into machine language; libgcj, a collection of standard Java class libraries; and GIJ (GNU Interpreter for Java), a Java virtual machine (JVM).

		The output of that compiler is (binary) object "p-code" (stored in a.class file, which is often compressed into a.jar PKZIP-compatible archive) for the virtual machine Sun intended all Java code to run on -- "Java bytecode".
		That minus the compiler is a JRE (Java Runtime Environment, i.e., everything to run Java bytecode, but not to compile it).
		Sun would prefer that all Java code end up compiled down to nothing lower than the Java virtual machine (compiled to bytecode), on grounds that compiling it further (to native machine code) "destroys portability, which is one of the main benefits of Java" (Java Programmers' FAQ, section 4, question 4).

		Normally, GNU C++ will automatically detect when you are writing C++ code that uses Java exceptions, and handle them appropriately.
		It is believed to be safe to throw a C++ exception from one file through another file compiled for the Java exception model, or vice versa, but there may be bugs in this area.
