I am getting an error when deploying an ice-faces 4.2 JSF app. I've included a snippet from the logs to see if anyone recognizes something. I don't know what else to include. Our environment is Liferay DXP SP3, Maven, faces.api.version 2.2. Anyone have an idea why this might be happening. Notably, none of my code is in the stack-trace, so it's a side-effect of what I'm doing, I think. Thanks ahead of time for any advice!
Here is the log:
