java modular-java reflection Java

I'm working with a `ClassNotFoundException` when trying to use reflection to access classes in a modular Java application (Java 11). Specifically, I have a main module that uses reflection to load a class from another module. My setup includes the following modules: - `com.example.main` (main module) - `com.example.utils` (utility module with a class `Utils`) I've specified the module dependencies in the `module-info.java` files appropriately, but I'm still working with issues. Here's a simplified version of my code: ```java // In the main module module com.example.main { requires com.example.utils; } // In the utils module module com.example.utils { exports com.example.utils; } ``` And here's the snippet where I'm trying to load the `Utils` class dynamically: ```java try { Class<?> utilsClass = Class.forName("com.example.utils.Utils"); // Work with the class... } catch (ClassNotFoundException e) { e.printStackTrace(); } ``` However, when I run my application, I get the following behavior: ``` java.lang.ClassNotFoundException: com.example.utils.Utils ``` I have confirmed that the `Utils` class is in the `com.example.utils` module and that I'm building the application with Maven. I've also set the module path correctly in my IDE's run configuration. Has anyone experienced this scenario or have any ideas on what might be going wrong? I've tried adding the `--patch-module` option to include the class at runtime, but it doesn't seem to resolve the scenario. Any help would be greatly appreciated!
