A 2-edged sword.
Of course this is clearly a bug in the EE-6 spec and not in CDI.
Otoh I don't like to have the EE umbrella spec impose rules on a CDI container. They
really are not allowed to impose such rules on CDI in the first place, isn't?

Subject: [cdi-dev] Fwd: [jsr342-experts] CDI in Application Client Container
All,
It's come to light that whilst the CDI spec explicitly does not require
support for the Java EE client container, the Java EE spec does require support
for it. There are no TCK tests for this.
The Java EE spec leads would like to rectify this by changing the CDI spec to
require support for it, however, I would prefer to alter the Java EE spec and
recognise this as a bug in the Java EE spec. IMO this relates very closely to
Java SE support, which I we want to address in CDI 2, not in 1.1.
Thoughts?

I'll be doing more test to make sure and fill a bug if needed.

If it's not working, please file bugs.

at the EE spec (eg. EE 7 - Figure EE.2-1) you see that CDI & DI is in the
ACC. But on the other hand, the CDI 1.0 spec (12.1. Bean archives) says
"The container is not required to support application client jar bean
archives." I tried several time with the appclient from GlassFish, and CDI
just doesn't work (wonder if JBoss ACC allows CDI or not). The "is not
required" part is frustrating.

Wouldn't it be useful to add it in EE 7 ?
