Zip contains parameter with Mono<Void> type

Reports zip operations that contains arguments with Mono<Void> return value inside a Reactor chain.

Zip completes empty as soon as incoming Mono<Void> completes. The quick-fix suggests replacing zip() and zipWhen() and zipWith() with when.

Example:, Mono.fromRunnable(() -> System.out.println("value"))) .map(v -> "New value") .doFinally(System.out::println);

After the quick-fix is applied:

Mono.when(Mono.just(1), Mono.fromRunnable(() -> System.out.println("value"))) .then(Mono.fromCallable(() -> "New value")) .doFinally(System.out::println);
