Reflection in an object-oriented system allows the structure of objects and classes to be queried at run-time, thus enabling "meta-object" programming such as program debugging. Remote Reflection allows objects in one address space to reflect upon objects in a different address space. Used with a debugger, remote reflection makes available the full power of object-oriented reflection even when the object examined is within a malfunctioning or terminated system. We implemented remote reflection as an extension to an interpreter to create a very effective debugger for Jalapeno, a Java Virtual Machine written in Java.
