The class loader based ENCFactory really should be dropped for a thread or invocation context keyed implementation. The main issue in switching is getting all of the component calls paths tied into the correct lookup mechanism. We also need a jndi Context wrapper that allows the enc context to be read-only. This should be a common ENCMap bean that provides the various enc Contexts keyed by a unique component deployment id. The id key is what needs to be made available for the java:comp ObjectFactory via thread local or invocation context key.
