Hi!
@javax.inject.Singleton is completely underspecified in JSR-330 and thus deliberately left
out in the CDI spec at all.
If I get back to Wards original Singleton definition "Singleton means to create
exactly one single instance (of a certain kind) in a well specified context" then the
@Singleton is exactly worth nothing. Because it doesn't say anything about in _which_
context it should behave like a singleton!
Is it 1 instance per Java VM? 1 instance per EAR? 1 instance per WAR?
The EJB singleton is at least clear that it's 1 per EAR.
LieGrue,

It's not currently on the agenda, but if the EG feel it's of sufficient confusion,
we can look at what this would mean.
