Background Java Agent technology can dynamically modify Java application behavior without reworking the code. It is because of these features that many middleware teams, cloud vendor teams, and open source products, started using Java Agent technology to provide some basic capabilities, such as Apache Skywalking, OpenTelemetry all provide Java Agent. Earlier, middleware teams provided capabilities through SDKs (e.g., observable, microservice governance capabilities, etc.); however, each time middleware teams added new features and fixed defects, they needed each business party to update the SDK version and re-release it.
