Shouldn't CompositeException be in here as well? While technically they're always undeliverable, they're very crash-worthy exceptions since they indicate an error while processing an error.

Updated. A few tests have been reverted from assertUndeliverable to assertError. I've also added an isBug unit test.

This PR adds the
UndeliverableExceptionandProtocolViolationException. The former wraps exceptions that happen beyond the lifecycle of a flow and the latter is added to distinguish validation bugs.The
RxJavaPlugins.onErrorwraps errors intoUndeliverableExceptionunlessRxJavaPlugins.isBug()returns true when theThrowableis relayed to the (default) handler.Having the
UndeliverableExceptionshould help with understanding the source of a crash and by having its own stack trace, help locating the offending positions (for example, a missedisDisposed()check in a 3rd party library).
