Appletviewer's classloader trying to load class with wrong name
throws ClassFormatError instead ClassNotFoundException.

==== Here is the test demonstrating the bug ====

___TestApplet1.java___

import java.applet.*;

public class TestApplet1 extends Applet {
  public void init(){
    ClassLoader cl = this.getClass().getClassLoader();
    if (cl != null) {
      try {
       Class cls = cl.loadClass("asdf.qwer.Str");
       System.out.println("OKAY");
      } catch (Exception ex) {
        System.out.println(ex);
      }
    } else {
      System.out.println("ClassLoader == null");
    }
 }
}
