SwAccessibleContext::Dispose called revokeClientNotifyDisposing,
which removed the SwAccessibleContext's id from its map, and then
called disposing() for all listenera of the SwAccessibleContext.
When one of the listeners, in its disposing(), tried to call
broadcaster's removeAccessibleEventListener, this violated the
API: XEventListener::disposing documentation directly prohibits
calling any methods of the broadcaster.
This was obviously a confusion, already present in commit
a18bdb3bc0 (Integrate branch of
IAccessible2, 2013-11-19), where the semantics of disposing()
was thought as "the listener is disposing", when in fact, it's
broadcaster notification about broadcaster's disposal.
