Markus Weimer commented on REEF-1345:
-------------------------------------

I'm in favor of using {{Exception}}s, as they convey the stack trace in addition to the message.

> For IMRU fault tolerant, we need to identify where to throw proper exceptions with error
messages in places where exception may happen. It includes: 
> TaskFailByCommunication - if there is any error caused by group communication, typical
case is when a task is not able to get messages from its children, this exception should be
thrown .
> TaskFiledByAppError - catch possible application error and throw the corresponding excretions
in those cases. 
> TaskFailedBySystem - any possible system error that could crash the task such as memory,
hard disk, file access, network, etc.
