Just for historical accuracy (not that anyone cares)... ;)
I looked back at the 2.2 spec and, as Yoav mentioned, it doesn't say anything about class loading order from the /classes and /lib directories. Although WL61 is 2.3 non-final compliant, apparently the ordering clarification didn't make it into that release.

WL6.1 is Servlet Specification 2.2-compliant, not 2.3. I think that loading order may have been a clarification in 2.3, though always intended to be this way, so tomcat is (and has always been) correctly implemented in this regard.
