What you can do

• Check whether a class is loaded, or where the class is being loaded. (Useful for troubleshooting jar file conflicts)
• Decompile a class to ensure the code is running as expected.
• View classloader statistics, e.g. the number of classloaders, the number of classes loaded per classloader, the classloader hierarchy, possible classloader leaks, etc.
• View the method invocation details, e.g. method parameter, return object, thrown exception, and etc.
