Seems to fit the main usage we have in jboss aop. Later when using the mdr in aop we can create the mdr signatures from MethodInfo etc

Maybe as Ales says we should not have MutableCI as parameters. If just CI is used, we can check internally if it is of the correct type (JavassistClassInfo), otherwise fall back to the String impl and look it up from the name. It saves us having to look it up every time.

That is an implementation detail that needs to be reworked internally. Having Class as the key for this won't work since we don't want the class to be loaded. Internally the weak type cache stores class names in a map of cl, so this methods can work

The use of WeakClassCache by Javassist will need revisiting so that it does not try to load the class every time we try to look something up since that is not needed by the underlying implementation.

Create a wiki page with the work in progress?
