RxJava 1.2.3, possibly 1.2.5 as well.

It runs inside Yigit Boyar's job queue like so:

    TrueTimeRx.build()
            .withLoggingEnabled(BuildConfig.DEBUG)
            .withSharedPreferences(applicationContext)
            .initializeRx("time.google.com")
            .subscribeOn(Schedulers.io())
            .observeOn(Schedulers.immediate())
            .subscribe(object : Subscriber<Date>() {
                override fun onError(e: Throwable) {
                    // Log.
                    Crashlytics.logException(e)
                }

                override fun onNext(t: Date) {
                    val i = Instant.ofEpochMilli(t.time)
                    // Log.
                }

                override fun onCompleted() {
                }
            })

The stack trace would be less horrible if I didn't originally rethrow the error in onError (heh), but I think I got the origin right.

@consp1racy : actually i'm curious now. your stack trace indicates that no bestResponse was received.

Can you confirm this (if you had logging enabled)? For e.g. the filterLeastRoundTrip should also have shown an empty list

I would filter out empty responses and we wouldn't run into the issue. but i want to make sure that really was the problem.

@kaushikgopal I'm afraid it happened on a remote device and the only thing I have is that stack trace :/

No best response is ok however something along a specific NoBestResponseException would be perfect.

oh wouldn't Crashlytics have the stack trace?

Well yeah, it's the whole second comment, kinda surprised you missed it :D

That's before I removed the throw e from onError. I'll post something cleaner as soon as it happens again but RxJava is known to produce messy stack trace anyway.

Basically the same thing on another device.

Yes, looks like TT is trying to onNext a value from an empty array instead of onError.

@consp1racy i realize why my comment was confusing now: i mean to say log trace not stack trace :). was not sure if you piped that to Crashlytics.

in any case i found a similar issue in our Crashlytics data, so should have this fixed
