I vendored two projects in my go project. And I successfully compiled my project. When I ran my project, it reported error "panic: http: multiple registrations for /debug/requests" . The detailed errors is shown below.

Does anyone have any idea on how to fix it? I guess it's because the two projects I imported both listen on /debug/requests?
                This is why it's dangerous for libraries to do this sort of thing in init functions. They should only register handlers when you explicitly tell them to.

                Thank you. @Volker @Adrian. I found the reason. It's because of the golang.org/x/net/trace project. In it's init() function, they handle the debug/request with hard code. So if two projects both import that library, then there is a conflict.

                Does anyone know a way to figure out WHAT package is responsible for the "double" vendoring?
