DocumentUimaImpl should deal with exceptions when change events are broadcasted
-------------------------------------------------------------------------------
Key: UIMA-2281
URL: https://issues.apache.org/jira/browse/UIMA-2281
Project: UIMA
Issue Type: Improvement
Components: CasEditor
Reporter: Joern Kottmann
Assignee: Joern Kottmann
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.
