> Trying to remove a listener that doesn't exist throws an IllegalArgumentException throws an exception. This is rather intolerant and annoying. Generally it would seem better to just ignore the call. (The listener is removed, right?)
> Aside from the obvious reproduction case of just calling {{removeListEventListener}} twice, this can be seen by calling {{dispose}} twice on a FilterList. Here's an example trace:
> {noformat}
> Caused by: java.lang.IllegalArgumentException: Cannot remove nonexistent listener [...toString of listener snipped...]
