为什么匿名内部类不包含从此代码生成的任何内容？

package com.test;

public class OuterClass {
    public class InnerClass {
        public class InnerInnerClass {

        }
    }

    public class InnerClass2 {

    }

    //this class should not exist in OuterClass after dummifying
    private class PrivateInnerClass {
        private String getString() {
            return "hello PrivateInnerClass";
        }
    }

    public String getStringFromPrivateInner() {
        return new PrivateInnerClass().getString();
    }
}

当javac在命令行上运行时Sun JVM 1.6.0_20,此代码生成6个.class文件:

OuterClass.class
在OuterClass $ 1.class
在OuterClass $ InnerClass.class
在OuterClass $ InnerClass2.class
在OuterClass $ $将InnerClass InnerInnerClass.class
在OuterClass $ PrivateInnerClass.class

在eclipse中运行JDT时,它只生成5个类.
