Jan-Kees van Andel commented on MYFACES-2509:
---------------------------------------------
Hrm, it looks like the JavaDoc can be interpreted in multiple ways.
What I read, is that it should be possible for classes that implement
SystemEventListener, to listen to SystemEvents.
For example:
http://java.sun.com/javaee/javaserverfaces/2.0/docs/api/javax/faces/event/PostConstructApplicationEvent.html
The current implementation cannot deal with this event, because it occurs
before the ApplicationImpl code is invoked (there is no component tree at that
time). For this reason, we need to check it @startup.
But because its so ambiguous, I suggest to leave it out of the beta release.

> This is specified in the spec for global system events, see:

> It would be nice to have it in the beta.
