-------------------------------------
Also we should understand why we see a trend of seeing more InvalidPid error
since 2.5
> Enforce exception thrown for KafkaProducer txn APIs

> In general, KafkaProducer could throw both fatal and non-fatal errors as
> KafkaException, which makes the exception catching hard. Furthermore, not
> every single fatal exception (checked) is marked on the function signature
> yet as of 2.7.
> We should have a general supporting strategy in long term for this matter, as
> whether to declare all non-fatal exceptions as wrapped KafkaException while
> extracting all fatal ones, or just add a flag to KafkaException indicating
> fatal or not, to maintain binary compatibility.
