'All of the above' really isn't necessary. Some of the problems can be corrected easily with modern IDE reformatting and refactoring tools.

That leaves:
  • Inadequate / incorrect comments
  • Mystery side-effects
  • Magic numbers
  • Swallowing errors
  • Not checking input parameters, return values, null testing
Each of these problem areas can arise in code that is otherwise elegant. The problems themselves tend to be inter-related - you get mystery side-effects when you swallow errors, errors that arise from magic numbers (like array sizes) that aren't correct. They aren't amenable to simple fixes, in that each problem needs to be examined individually and an appropriate correction made.

My approach to this sort of thing has been to reformat and refactor until the code is in readable form, and then start defeating the remaining problems in detail.
Software Zen: delete this;
