Nope, search for "Weka", W-J48 will be inside weka package

Hello @mbs

Do you mean the W-J48 in the weka extension? If so, it works for me on 9.4.001.

Did you have a weka extension installed? You can check it in Extensions --> Manage Extensions and see there. If it is not there install it from the market place.
