Is this with WildFly 8.0.0.Beta1+ ?
JBoss EAP 6.0.1.Alpha1
I think I found the cause: I used a ironjacamar.xml inside the RAR, causing a duplicate definition.
the first definition made in standalone.xml declare my custom bootstrap context
the second definition made in ironjacamar.xml did not delcare the custion bootstrap context, so default was used
As far as I understand, I can't use both. removing ironjacamar.xml do the trick.
ironjacamar.xml is one activation, :resource-adapters: is a separate one.
So, use either one.
