Bug 108856 covers anonymous class, but the same bug exists for named classes.

Test file:

public class ClassNameTest {
    public static void main(String[] s) {
	new Object(){{
	    System.out.println(this.getClass());
	    System.out.println(this.getClass().getSimpleName());
	    new Object(){{
		System.out.println(this.getClass());
		System.out.println(this.getClass().getSimpleName());
		class X {{
		    System.out.println(this.getClass());
		    System.out.println(this.getClass().getSimpleName());
		}};
		new X();
	    }};
	}};
    }
}

Output when compiled with javac:

class ClassNameTest$1

class ClassNameTest$1$1

class ClassNameTest$1$1$1X
X


Output when compiled with Eclipse:

class common.test.ClassNameTest$1

class common.test.ClassNameTest$1$1

class common.test.ClassNameTest$1X
