Review Comment:
   'star' or 'start'?

Review Comment:
   'that is actually block' - is everything ok here?

Review Comment:
   Would it make sense to extract this to a method? I think it should be used 
at least twice. Having a method, the comment would become obsolete

Review Comment:
   You changed `Executor` to `ExecutorService` because 
`IgniteThrottledLoggerImpl` wants the latter, but in reality `Executor` is 
enough in the logger. I suggest to change `ExecutorService` to `Executor` in 
the logger and revert this part of the changes.
