Why this ClassCastException ???

i'm having a unusual ClassCastException in my code, then i do that test and
dont understand this result:

System.out.println(scroller instanceof HtmlDataScroller);
System.out.println(scroller);

12:27:37,531 INFO  [STDOUT] false
12:27:37,531 INFO  [STDOUT]
org.apache.myfaces.custom.datascroller.HtmlDataScroller@178ff42


Why this???

Another possibility is that you have two tomahawk jars in your
classpath, and you're using one class of HtmlDataScroller for each
one.

Adding the following line may provide more insight.

System.out.println(HtmlDataScroller.class.getName());
