A dynamic service module is embedded in an agent and able to add functionality to the agent. The service module may manage .jar files for execution by the agent. The service module may receive the .jar files, provide them to an agent for execution, and may perform other functions. The agent may perform obfuscation in order to translate the .jar files into a modified version which may be more compatible with a particular agent. Once execution of the .jar file is complete, the agent may remove the .jar file as well as all trace of the .jar file. For example, the agent may remove byte code instrumentation that was installed as a result of the .jar file.
