2.1.8

Maven

Warning! Behavior change regarding handling illegal calls with null in Processors and Subjects.

The Reactive Streams specification mandates that calling onNext and onError with null should
result in an immediate NullPointerException thrown from these methods. Unfortunately, this requirement was overlooked (it resulted in calls to onError with NullPointerException which meant the Processor/Subject variants entered their terminal state).

If, for some reason, the original behavior is required, one has to call onError with a NullPointerException explicitly:

PublishSubject<Integer> ps = PublishSubject.create();

TestObserver<Integer> to = ps.test();

// ps.onNext(null); // doesn't work anymore

ps.onError(new NullPointerException());

to.assertFailure(NullPointerException.class);
