I have struggled with Observable.combineLatest RxJava2. I could not even compile simple example like this

val obs1 = Observable.just(true)
val obs2 = Observable.just(false)
Observable.combineLatest(obs1, obs2, { t1, t2 -> t1 and t2 })//compile error

I had to explicitly tell what kind of combiner function that is

val obs1 = Observable.just(true)
val obs2 = Observable.just(false)
Observable.combineLatest(obs1, obs2, BiFunction<Boolean, Boolean, Boolean> { t1, t2 -> t1 and t2 })

In case JavaRx1 it was inferred properly based on observables I was passing in. Does anyone know why it has changed?
