CafeBabe (JDK1.1.x + Swing 1.1 or JDK1.2). This program will say you all about contents of complied code for JVM. It works as a graphical disassembler and displays full information about any sort of information enclosed in bytecode: field, methods, attributes, exceptions, synthetic members, method body, additional information inside code and so on. While virtual machine misses unknown attributes, CafeBabe displays all of them.

Main features of CafeBabe project are:

• program represents bytecodes "as is" - following the class file format specification: magic number, minor and major version, constant pool, access flags, this class, super class, interfaces, fields, methods and class attributes;
• program can read class files directly from archive (*.zip or *.jar) and it interprets them as directories, thereby you can travel inside archive for selecting desired file;
• program contains abilities for searching string inside bytecode;
• user can edit information inside constant pool (UTF8-string);
• ability to remove some optional information from bytecodes: inside methods body, source file attribute, unknown attributes;
• ability to perform migration of bytecodes disposed inside package from old to new namespace;
• ability to perform obfuscation of bytecodes disposed inside packages;
• ability to show/hide partitions of classfile.
• user can use this program as a tutorial - tooltips will explain to user what each byte (short, integer) inside bytecode means;
• user can quickly change its own location among installed classes and observe hierarchy tree (see Class-Hound Service);
