ProGuard Java Optimizer and Obfuscator
Eric Lafortune announced the release of ProGuard in version 4.2. ProGuard is a free Java class file shrinker, optimizer, and obfuscator. It removes unused classes, fields, methods, and attributes. It then optimizes the bytecode. It then renames the remaining classes, fields, and methods using short meaningless names.
It is an open source available, Java-based Obfuscating tool. ProGuard is distributed under the terms of the GNU General Public License (GPL), version 2, as published by the Free Software Foundation (FSF). The new version is primarily a bug fix release.
