Review comment:
Thanks for taking a look @vlsi .
When we create the model/types we rely more or less on the same methods
(e.g.,
https://github.com/apache/calcite/blob/3ccad7b2bcc962d48c1dee1c9604fd085d82c608/core/src/main/java/org/apache/calcite/jdbc/JavaTypeFactoryImpl.java#L75)
so in many cases the code should work fine I think. I don't know how we can
handle this better with the way the code is right now. Do you have a better
idea?
It's true that the exception should be updated. I will take care of it but
let's see if there are other things to do at the same time.
