Has anyone tried running Cayenne Modeler on macOS Monterey? I ran, or at least I tried, CM 4.2M3 to look at Lon's issue and CM wouldn't run. Tried a version I downloaded from the web site and the version I built previously for the 4.2M3 release cycle. Didn't see any messages in Console.app, but I didn't try to find other logs. I know the version I built previously ran on Big Sur at the time, otherwise I wouldn't have +1'ed it.
Running the generic JAR works. Thanks, mrg
