-------------------------------------

[~joshrosen]  I didn't merge this in 1.6.2 because it is a bit too big to 
backport. Let me know if you want to create a smaller patch for 1.6.


> Catch, wrap, and re-throw exceptions from Await.result in order to capture 
> full stacktrace

> When {{Await.result}} throws an exception which originated from a different 
> thread, the resulting stacktrace doesn't include the path leading to the 
> {{Await.result()}} call itself, making it difficult to identify the impact of 
> these exceptions. For example, I've seen cases where broadcast cleaning 
> errors propagate to the main thread and crash it but the resulting stacktrace 
> doesn't include any of the main thread's code, making it difficult to 
> pinpoint which exception crashed that thread.
