A Null Pointer Exception in DeafultCoordinator #80

Closed samira-t closed 11 years ago

samira-t commented 11 years ago

I am developing a testing framework for testing actor systems. I ran my tool on Signal Collect and I noticed there is a bug in DefaultCoordinator. In fact, when the workers are created, they may receive a TimeoutMessage and call sendStatusToCoordinator. Upon calling that, the coordinator send Heartbeat messages to workers. However, if the workers has not been initialized in coordinator, there would be a null pointer exception.
