IllegalAccessException after updating 2.1 to 2.2

Sorry about this. I thought that this had been fixed before the 2.2 release, but it was not. A similar issue was raised a while back with respect to injection of the "location" and "resources" fields. If a legacy class defined one of these fields and was not properly annotated, injection would fail. This was fixed such that FXMLLoader now ignores IllegalAccessException when injecting those fields, but I did not think to make a similar change for the initialize() method.
Can you please file a bug report? Thanks.

Apparently the 2.2 loader looks for an "initialize" method in the controller and its super classes. In my case it finds a protected initialize() in a legacy super class which is used in Swing. Later on it fails to invoke that initialize() because it is not made accessible (having no @FXML annotation, of course).
