Reports lambda formal parameter types that are redundant because they can be inferred from the context.
Example:
Map<String, Integer> map = ...
map.forEach((String s, Integer i) -> log.info(s + "=" + i));
The quick-fix removes the parameter types from the lambda.
Map<String, Integer> map = ...
map.forEach((s, i) -> log.info(s + "=" + i));
