They most certainly can do both, and do. But as a solver, I prefer to give it back to the person to solve. 1. I may know enough to know the problem and the rough fix. I may not know how to fix it in their codebase as quickly as they do. 2. See above. I want them to internalize the fix. That said, I ain't afraid to dive in and get it done. I remember not understanding some Java build system somewhere. So I fixed the code, tested it quickly, and hand deployed the jar... then I asked how to fix it for real ;) My boss was amused.
