[cdi-dev] Can an observer be both async and sync?

[John Ament]

Section 10.4.4 has the following section which got me thinking


public void refreshOnDocumentUpdate(@Observes(notifyObserver=IF_EXISTS) @Updated Document doc) { ... }

public void asyncRefreshOnDocumentUpdate(@ObservesAsync(notifyObserver=IF_EXISTS) @Updated Document doc) { ... }


I'm wondering, is it OK to have an observer method defined like this?


public void asyncRefreshOnDocumentUpdate(@Observes(notifyObserver=IF_EXISTS) @ObservesAsync(notifyObserver=IF_EXISTS) @Updated Document doc) { ... }


I don't see anything against this in the spec, but I suspect most people are going to think this shouldn't work.  So I'm asking the question - should it work?
