Problem with Jackson and RxJava

See original GitHub issue

Goal

Use Realm and Jackson without RxJava dependency.

Actual Results

The Realm docs suggest to add empty Observable and Flowable classes but Realm checks the existence of io.reactivex.Flowable to determine if rx is available and crashes. Here is the relevant line.

java.lang.NoClassDefFoundError: Failed resolution of: Lio/reactivex/BackpressureStrategy;
at io.realm.rx.RealmObservableFactory.<clinit>(RealmObservableFactory.java:79)
at io.realm.RealmConfiguration$Builder.build(RealmConfiguration.java:806)
at io.realm.Realm.init(Realm.java:247)
...

Version of Realm and tooling

Realm version(s): 4.1.0

Well, we are getting there 😄

I guess the solution will be

package io.reactivex;

class Observable {
}

and

package io.reactivex;

class Flowable {
}

and

package io.reactivex;

enum BackpressureStrategy {
    LATEST;
}

And then it should work.
