Instances of a JavaCassMirror provide unified access to
Java reflective data (expeccially to methods, constructors and
fields) as required by Java reflection API.
Different classes may use different mirrors - for example,
Smalltalk classes use a special mirror so non-Smalltalk classes
and instances could be introspected and manipulated by standard
Java code.

reflection ... now always a JavaVM reflection.
