[jboss-as7-dev] AS7 Naming behaviour change for Context#list and JNDI View

[Eduardo Martins]

I checked the concrete use case for Naming subsystem bindings, these are done using ValueManagedReferenceFactory, which was one of the upgraded factories.

From now on lookups will only be done for entries which do not use ManagedReferenceFactory as a mean to return the lookup value, and for these special entries the Naming module will now return safe default values, Object.class for list operations, and the String "?" as the value printed in JNDI View.
