public class DataReflection1
extends Data

DataReflection1 creates tables which the JNI interface will use. This includes:

1. a table to map class names to java.lang.Class objects, sorted in order of the UTF-8 encodings of the class names. (begins at name2class_start, ends at name2class_end)
2. a table to map java.lang.Class objects to class information structures, sorted in order of the (non-relocatable) Class object address. (begins at class2info_start, ends at class2info_end)
3. UTF-8 encoded class name strings, used by the first table as well as by the class information structures.
4. Static java.lang.Class objects. As the JDK dictates, these contain no actual class data; however, table #2 above can be keyed by the object address to fetch the actual class information structures.
