Re: [Resteasy-developers] resteasy-cdi problem in wildfly 8CR1

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Log a JIRA and I'll forward it to the apropriate people.  I don't think 
I have the knowledge to fix this.  We made a change in wildfly that all 
JAX-RS instances are managed by CDI because of managed beans and such. 
Maybe it is just a matter of Weld making better decisions about what is 
and what isn't a CDI bean.
