FreeMarker

When trying to use a jsp simple tag, I got this exception:
java.lang.ClassCastException: freemarker.ext.jsp.SimpleTagDirectiveModel

I looked at TagLibFactory.TagLib. The casting on line 393 seems a little
overly restrictive. This is fixed in trunk, but somehow didn't get into
2.3.11, I guess.
