Yes.

I currently use what the Reflect is using,
so you don't do double work, but I guess that might not be the best thing.

We can switch Scanning to use different ReflectProvider:
* http://anonsvn.jboss.org/repos/jbossas/projects/scanning/trunk/scanning-impl/src/main/java/org/jboss/scanning/plugins/visitor/ReflectProvider.java
if that turns to be an issue.

This is where you switch it:
* http://anonsvn.jboss.org/repos/jbossas/trunk/server/src/main/java/org/jboss/deployment/ResourceUtilSetupDeployer.java

I have this Javassist based RP impled:
