Description

The DocumentUimaImpl class is responsible to broadcast CAS change events to all registered listeners. If one of these listeners throws an exception while notified about a change the listener call loops pass the exception on the the caller.

This means that a faulty listener can "crash" the Cas Editor because the change notification is necessary for synchronizing all views.

To make this more robust the SafeRunner should be used, which will catch and log any exceptions.
