JarSpy is a utility for "spying" the contents of Java archive files. The current beta release allows read only access into an archive. This read only access allows the inspection of all of the classes and interfaces contained in the archive. For each class or interface, a list of methods, fields and dependencies are available. Planned functionality includes the ability to modify the contents of an archive using JarSpy. These changes may include the ability to obfuscate the contents of an archive.
