Head commit for run: a474a77242058aaed81dbae38eef17674bd68316 / James Daugherty <[email protected]> Carry null through the RxJava 3 promise factory grails-async-rxjava3 did not behave like the other promise factories for a promise of null. RxJava 3 forbids null in a stream and the factory passed it straight in: createPromise(), createPromise(Class) and onComplete over a list holding a bound promise of null threw NullPointerException from Single.just/Observable.just, and createPromise { null }.get() returned the java.lang.Void class that runCallable used as a sentinel and nothing turned back. createPromise() is what Promises.createPromise() and WebPromises.createPromise() call. RxPromise now carries null through the stream as a private sentinel and restores it wherever a value leaves the stream: get(), the value an onComplete callback receives, and the lists onComplete, onError and waitAll deliver. RxPromiseNullSpec covers each case and fails on the previous code; the result == Void assertion in RxPromiseSpec becomes result == null.
