  "description_en": "Krakatau assembles and disassembles Java bytecode, including obfuscated class files, and can reassemble the text back into a class file. krak2 dis writes assembly, and --roundtrip keeps a bit-for-bit reassembly. krak2 asm assembles .j files. The assembler syntax covers the Java 27 bytecode specification. The v2 decompiler is unfinished, so decompilation still uses Krakatau v1 on the master branch. cargo build --release produces target/release/krak2.",
