Review Summary
Your implementation is functionally complete and well-structured, but there's a checklist violation that needs to be fixed. On line 54-55 in Injector.java, the caught ReflectiveOperationException is not passed as the cause parameter to the RuntimeException. This violates checklist item #7. Without proper exception chaining, debugging becomes significantly harder since the original stack trace is lost. The fix is straightforward: change throw new RuntimeException("Can't create an instance of " + clazz.getName()); to throw new RuntimeException("Can't create an instance of " + clazz.getName(), e);. Once this is corrected, your solution will fully meet all requirements.

Checklist item #7 violation: The caught exception should be passed as the cause parameter to the RuntimeException. This makes debugging easier as the full stack trace will be preserved. Change to: throw new RuntimeException("Cant create an instance of " + clazz.getName(), e);

Review Summary
Your implementation fully meets all requirements and passes every checklist item. The dependency injection system is correctly implemented with @Component and @Inject annotations, proper @Retention(RUNTIME) and @Target configurations, instance caching in the Injector, informative exception messages, and proper exception chaining using ReflectiveOperationException. All previous review comments have been addressed, including the exception chaining fix. There's only a minor cosmetic suggestion: the error message on line 55 could use "Can't create" instead of "Cant create" for consistency, but this doesn't affect functionality. Excellent work on this implementation!
