-/**
- * A class that does bean introspection on a JDT IType
- *
- * This functionality is not meant to replace runtime bean
- * introspection. Rather, it is meant to provide a
- * more "lightweight" (in terms of class loading as well as
- * error handling of bean instantiation out of context) way
- * to determine a bean's properties at design time.
- *
- * This class may not be sub-classed by clients.
