Method.invoke should initialize its class before invoking the method,
throwing an ExceptionInInitializerError if it fails, without wrapping
said error in an InvocationTargetException.
Also, we must initialize ExceptionInInitializerError.exception when
throwing instances from the VM, since OpenJDK's
ExceptionInInitializerError.getCause uses the exception field, not the
cause field.
Inner classes can have inner classes, but getDeclaredClasses() is
supposed to list *only* the immediate inner classes.
Example: if class Reflection contains a class Hello that contains
a class World, Reflection.class.getDeclaredClasses() must not
include World in its result.

When the class whose field is to be inspected has no annotations at all,
at least my javac here (1.6.0_51 on MacOSX) does not produce any class
addendum.
Therefore, let's verify that the addendum is not null before proceeding.

The VM uses Integer and Long instances internally to wrap the results
of dynamic method invocations, but Method.invoke should use the
correct, specific type for the primitive (e.g. Character for char).
