Tattletale analyzes Java classes in archives (JAR, WAR, RAR, EAR) and builds HTML reports that

• Identify runtime (bytecode) dependencies between archives on a class/package level
• Find missing classes from the classpath
• Spot if a class/package is located in multiple archives
• Spot if the same archive is located in different places
• List what each archive requires and provides
• Verify the SerialVersionUID of a class
• Find similar archives that have different version numbers
• Find archives without a (valid) version number
• Find unused archives
• Identify sealed/signed archives
• Locate a class in an archive
• Show the OSGi status of your project
• Identify blacklisted API usage
