BUG FIX: ConstantReader.revive() now properly returns no URL fragment
when the constant expression is resolved from a top-level or static-field.
The documentation had said otherwise, and it was impossible to tell the
difference between a constructor and a field. Now, fields are always in
the form of accessor = {clazz}.{field} or {topLevelField}.

Fix file URIs on windows.
