Java Agent Programming is a powerful feature that allows developers to instrument Java bytecode at runtime. This capability is incredibly useful for profiling, monitoring, logging, and many other advanced functionalities that require altering the behavior of Java applications without modifying the source code. What is a Java Agent? A Java Agent is a special type of library that can be attached to the Java Virtual Machine (JVM). It can be used to modify existing classes or load new ones.

This blog post is about writing a Java agent and instrumentation code to find unused classes and dependencies in your project. Knowing which classes and dependencies are not used in your application can save you from considering the bugs and problems in these dependencies and classes. There a multiple tools out there, for gradle and maven (thanks, Marit), that do this statically or dynamically (like the one described in the paper Coverage-Based Debloating for Java Bytecode, thanks, Wolfram).
