handling of IndexOutOfBoundsException the DocumentFocusListener::notifyEvent() throw list only allows a RuntimeException to propagate. The methods called in notifyEvent() allow IndexOutOfBoundsException though, so it must be handled in all cases to prevent C++ from invoking its unexpected() abort mechanisms. Ceterum censeo, non-empty throw lists should be removed altogether...
