Java is a beautiful and capable language. I have written ORMs in both Java and Go, and the former was much easier to implement. Java has a culture problem though where developers seem to somehow enjoy discovering new ways to complicate their codebases. Beans are injected into codebases in waves like artillery at the Somme. Errors become inscrutable requiring breakpoints in an IDE to determine origin. What you describe with debugging a HTTP handler in your Go project is the norm in every commercial Java project I have ever contributed to. It's a real shame that you are seeing these same kinds of issues in Go codebases.
