---------------------------------------------

Can you share the code of the Nvl class, or even better a small self-contained reproducer?

> Exception in thread "main" java.lang.AssertionError: not a literal: NVL($0, 2)
> // trace
> // `NVL` is a scalarFunction that likes oracle nvl function. And this exception might be thrown from this code in my  `getTypeInference` function of ROUNDX scalarFunction.
