Mura/ORM reload error after upgrade from Railo

Uploaded from Railo to Lucee on my local environment according to the instructions.

Some sites work fine, as do the admin pages. But on trying to load a MuraCMS site, I get the following error. Looks like it's from one of my plugins - FW/1-based - when it calls ormReload():

java.lang.NoClassDefFoundError

My installation folder still has the following jars in it - is that correct?

railo-inst.jar
railo-sl4j.jar
