[JIRA] (GLAZEDLISTS-419) removeListEventListener throws IAE for nonexistent listener

JIRA jira-no-reply@java.net

     [ https://java.net/jira/browse/GLAZEDLISTS-419?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

reden resolved GLAZEDLISTS-419.

    Resolution: Fixed

Change pushed in commit 88c18801c014bbfff766a3101ee06705a3856d46.

By default SequenceDependenciesEventPublisher no longer performs that check. To allow for compatibility, I added the system property "-Dglazedlists.compat.nonexistent_listener_check" which can be set to re-enable the check.

> EventList.removeListEventListener throws an IllegalArgumentException when passed
> an nonexistent listener.  Fine, but this behavior is not the same as
> javax.swing.event.EventListenerList, which fails silently.  Compounding the
> issue is that there is not a ListEventListener[] getListenerList() or similar
> method for clients to check against before calling remove.
> Possible remedies:
>  - implement removeListEventListener to fail silently
>  - add a new method removeListEventListenerIfPresent(ListEventListener) that
> fails silently
>  - add a new method ListEventListener[]/Collection<ListEventListener[]>
> getListenerList() or similar
