This method is intended to be used in conjunction with 
Constructor.newInstance, Method.invoke, Field.get, ...  The idiom in 
Peter's mail combines this with trySetAccessible and makes it easy to 
gracefully handle cases where access is not allowed.

JEP 274 added Lookup.accessClass and may be closer to what you need.
