Spoon-decompiler is an extension of spoon that allows working on bytecode by decompiling it (using your favorite decompiler, or one of those already included). This can be done offline with the help of JarLauncher or DecompiledResource, as well as at loadtime in an agent or a classLoader with the help of SpoonClassFileTransformer.
