The usage of the IssueLinkDeletedEvent within a selfmade listener is unclear

Hi!

(1.)
The usage of IssueLinkDeletedEvent is totally unclear to us.
We use to have listeners, which compare the EventType within the onIssueEvent method to a special Event, but this doesn’t work with the IssueLinkDeletedEvent, as it cannot be choosen.
For example:

@com.atlassian.event.api.EventListener
public void onIssueEvent(IssueEvent issueEvent) {

Long eventTypeId = issueEvent.getEventTypeId();
if (eventTypeId.equals(EventType.ISSUE_MOVED_ID)) {
LOGGER.trace("Event Type is MOVED: " + eventTypeId);
return;
}

Please provide information (sample code snippet?) on the usage within a custom listener.
We see, that it is not in the com.atlassian.jira.event.type EventType class, but would have expected to find it there. (We use Jira 7.6.4)

(2.)
System > Advanced > Events doesn’t show neither the IssueLinkCreatedEvent nor the IssueLinkDeletedEvent. Is this usual?

(3.)
Even https://docs.atlassian.com/software/jira/docs/api/7.11.0/com/atlassian/jira/event/issue/link/IssueLinkDeletedEvent.html\ shows a wrong description “…Signals that an issue link was created.”

Any help is appreciated!
Thanks in advance.

Kind regards,
Patrizia
