[Struts-src] Creating a form-bean

[Sri Sankaran]

I was wading through the source code to figure out the process of creation of a form 
bean and found the following snippet in o.a.s.u.RequestUtils in the method 
createActionForm (line 654 in the 1/28 nightly source):

(beginning at line 709)

if (configClass.isAssignableFrom(instance.getClass())) { 
  if (log.isDebugEnabled()) {
    // snip
  }
  return (instance);
}
return (instance);

Can you tell me what this the if-statement is accomplishing?  It looks like 'instance' 
will be returned regardless.
