Controller is not executed -> Message Overflow #2

Closed d-krupke closed 9 years ago

d-krupke commented 9 years ago

I observed some Message Overflows induced by the StateManager (which only sends one Message per Timestep). As the Message Queue is cleaned in each timestep this is kind of funny because a robot should at most receive one StateManager-Message from each robot, but this time it where far more than robots where in the simulation. As I tried to move this robot by the left-mouse, it failed. It seems like the robot is not looped at all. At this moment I have absolutly no idea and I observed this only with my new algorithms (which use more messages). There should be no possibility for a controller to kill itself without an exception. Also I have no idea how to reproduce this (it happens in like 10% of the runs). It is possible that this bug has been unnoticed for a long time, as I still fix Synchronization Errors from time to time (Especially in the Visualization).

It looks like as if Assertions are swallowed and lead to this issue without any notification. They are not catched but the finally block is called. I don't think that Java always behaved liked this, because it is stupid.
