They are absolutely the ones to create hard-to-debug issues because they layered a whole bunch of complex things incorrectly or unknowingly. For example, recently I spent more time than I'd like finding out that we linked two incompatible versions of a library. All the visible dependencies were correct, but at some point someone bundled an old version in a fat jar and that got included transitively via another dependency. If you understand the details you know why you don't distribute libraries as fat jars. But if you're just following some guide it's easier to fat jar it than correctly specify your dependency tree. If your education was really effective you recognize this is just the static/dynamic linking problem again in new clothes.
