While writing my plugin, I noticed that a bug got introduced between 2.1 and 2.1.4: Example code:

public void handleEvent(ConfluenceEvent event) {
if (event instanceof PageUpdateEvent)

{ Page page = ((PageEvent) event).getPage(); AbstractPage orig = ((PageUpdateEvent) event).getOriginalPage(); this.logger.debug("Page \"" + page.getTitle() + "\" in space \"" + page.getSpaceKey() + "\" updated"); this.logger.debug("Original \"" + orig.getTitle() + "\" in space \"" + orig.getSpaceKey() + "\" updated"); }

}

Both the orig.getSpaceKey() and the orig.getSpace() return null, which is kind of useful when listening on page events such as update or remove are intercepted (how do I know if a page was moved from one space to another?).
