The problem is that the BuilderV2 interfaces have getBuilder and getRepository that mismatches the setBuilder & setRepository on the sub-interface. This causes intermittent problems with the Freemarker & webwork. If we rename the methods on the top level interfaces (suffix with V2) that should be fine
