> If some exception occurs in a StateMachine implemented method, the exception is propagated back to Ratis and then through Ratis back again to StateMachine. In this back and forth, the exception could be lost. 
> While working on OM Bootstrap, I encountered a NullPointer exception in OMStateMachine which cause Ratis (and eventually StateMachine) to shutdown with a "client cancelled" exception. It would have helped in debugging if the OMStateMachine had logged the initial exception.
