Odd reflection issue

[Timothy Reaves]

        I'm not sure what is going on with what I'm doing, so thought I'd ask for 
some help.  My environment is Sun JDK 1.3.

        I am trying to understand reflection.  When I run the command 'java 
com.bascom.TestClass3' from a terminal, I get this output (I'm only 
pasteing in the pertanent part):
[treaves@double treaves]$ java com.bascom.TestClass3
4
Fields for TestClass3
=====================
Field 0: private int com.bascom.TestClass3.attribute3
Field 1: private java.util.HashMap com.bascom.TestClass3.hasmMapAttribute
Field 2: private java.lang.String com.bascom.TestClass3.lastAttribute
Field 3: private static java.lang.Class 
com.bascom.TestClass3.class$Ljava$lang$Object


This is what I get from BeanShell:
bsh % Class testClass = Class.forName("com.bascom.TestClass3");
bsh % Field[] fields = testClass.getDeclaredFields();
bsh % print(fields.length);
3
bsh % print(fields);
Array: [Ljava.lang.reflect.Field;@6f247 {
    private int com.bascom.TestClass3.attribute3
    private java.util.HashMap com.bascom.TestClass3.hasmMapAttribute
    private java.lang.String com.bascom.TestClass3.lastAttribute
}


        So when I run from the commandline, it lists that there are four fields, 
and in BeanShell it lists three.  The command line shows the 
java.lang.Class as the fourth field.  Why?  What am I missing?

        Thanks.
