Class EmptyMonoZip

java.lang.Object
com.google.errorprone.bugpatterns.BugChecker
tech.picnic.errorprone.bugpatterns.EmptyMonoZip
All Implemented Interfaces:

@AutoService(com.google.errorprone.bugpatterns.BugChecker.class) public final class EmptyMonoZip extends com.google.errorprone.bugpatterns.BugChecker implements com.google.errorprone.bugpatterns.BugChecker.MethodInvocationTreeMatcher
A BugChecker that flags Mono.zip(reactor.core.publisher.Mono<? extends T1>, reactor.core.publisher.Mono<? extends T2>) and Mono.zipWith(reactor.core.publisher.Mono<? extends T2>) invocations with a Mono<Void> or Mono.empty() argument or receiver.

When a zipped reactive stream completes empty, then the other zipped streams will be cancelled (or not subscribed to), and the operation as a whole will complete empty as well. This is generally not what was intended.
