Eclipse 2023-09: how to Debug Spring Boot Application with Conditional Breakpoints Set in Custom Annotations

Eclipse Spring-Boot Debugging Java

I've looked through the documentation and I'm still confused about I'm working on a Spring Boot application in Eclipse 2023-09 and working with issues when attempting to debug with conditional breakpoints set on methods annotated with a custom annotation..... My custom annotation looks like this: ```java @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface LogExecutionTime { } ``` In one of my service classes, I use this annotation: ```java @Service public class UserService { @LogExecutionTime public User getUserById(Long id) { return userRepository.findById(id).orElse(null); } } ``` I set a conditional breakpoint in the `getUserById` method using the expression `id == 1`, expecting the debugger to stop whenever I call this method with the ID of `1`. However, the breakpoint is never hit. I've verified that the application starts correctly and that the annotation is processed as expected. I even added logging to ensure the method is being called: ```java System.out.println("Fetching user with ID: " + id); ``` When I run the application, I see this log output confirming that the method is invoked with ID `1`, but the debugger simply skips over the breakpoint. I've also tried refreshing the project, cleaning and rebuilding it, and ensuring that the correct launch configuration is selected. The breakpoint is marked as conditional in Eclipse, but I suspect there might be an underlying scenario with how Eclipse handles conditional breakpoints on methods with custom annotations. Has anyone else encountered this question? Any suggestions on how to resolve this or work around it would be greatly appreciated! Has anyone else encountered this?
