| Summary: | Unnecessary compiler warning when lambda parameter is not used | ||

| Issue Type: | DEFECT | Exception Reporter: | |
The following code produces a warning on the parameter "a": ---------------------------------------------------------------- Stream.of(1, 2).filter(a -> true); Stream.of(1, 2).filter((Integer a) -> true); ---------------------------------------------------------------- The following code, however, doesn't: ---------------------------------------------------------------- Stream.of(1, 2).filter(new Predicate<Integer>() { @Override public boolean test(Integer a) { return true; } }); ---------------------------------------------------------------- The warning is not really necessary. It would be better not to report it (or at least make reporting it an option, and not report it by default)
