- Warn on empty statements, e.g. "for (;;);". These may be
typos and are easily replaced by "for (;;) {}" which is more
explicit.
- Warn on field hiding. This allows cleanup of many acceptance test
members, at the cost of a couple of renames and the occasional
suppression (when the field is in a public nested enum that shadows
a public constant).
- Warn on unnecessary casts.
- Warn on unused declared thrown exceptions. In addition to reducing
method signature length and number of imports, this also eliminated
some impossible catch blocks.
- Warn on missing @Override annotations.
- Warn on unused parameters. This is likely the most controversial,
as a few relatively common patterns require unused parameters in a
way that Eclipse can't ignore. However, it also resulted in cleanup
of a lot of unnecessary injections and method parameters, so I
think the cost was worth it.
