Log:
[JBREFLECT-6] Fix JavassistMemeberFactory to use the classloader of jboss-reflect when generating the JavassistMethod, -Constructor and -Field implementations if the class targetted lives in a parent classloader of jboss-reflect.
Add initial support for changing the implementation of how the accessors are created, i.e. normal reflection vs generated classes.
Add support for metrics of how often the accessors are called accessible via an MBean
