Review Comment:
   Wondering if we should merge both blocks and just catch `RuntimeException`? 
Seems to be duplicate code? And just pass in whatever exception we catch and 
rethrow as `new StreamsException(..., e);` -- this way we preserve the original 
exception and don't need to "awkwardly" add `e.getMessage()` for the first 
case.
