Review Comment:
   > Since you catch the exception and don't rethrow it, this current code just 
ends up logging (and not throwing exception/restarting the sdk).
   > 
   > I think that you could change the ExecutionStateSampler constructor to 
take in some function to call when this timeout has happened. Then for unit 
test you could just pass in some lambda that notifies a completablefuture or 
countdownlatch and verify it is called. In the real harness, you could pass in 
a function that call System.exit or otherwise ends up terminating the harness.
   
   The new fix just throws a runtime exception directly, but probably a try 
catch Timeoutexception then throw runtimeexception for consistency would be 
better(?) Personally, I would like not to add function to constructor as what 
you mentioned because it would potentially break many other tests that are hard 
to fix
