I am getting the below error in logs in SDL. This is related with ADF, I am not able to find the way to sort this out.

A ClassCastException happens when you try to cast objects of one type to a different type and the two aren't compatible.

I would guess that either you accidentally installed the wrong version of a JAR file, or that you have a cartridge configured that is built against an older, incompatible version of the ADF (although I don't think there's been any breaking changes so it seems unlikely). Or perhaps the cartridge itself refers to some third-party libraries that now have a newer version installed.

To find the cause, I would start by disabling all cartridges and re-enabling them one by one. If it happens without any cartridges configured, the problem is likely with your ADF installation/configuration. If it happens when a particular cartridge is used, you'll want to look into the specifics of that cartridge to find the cause.
