> As a movement to collated world, we need to make sure all expressions are supported by appropriate collations. Using expression walker testing `CallMethodViaReflection` was found to be erroneous. This expression is used as a replacement for all reflection methods and needs to be improved. This ticket needs to update methods of this expression. Relevant code could be found in these files: `CallMethodViaReflection.scala`, `TypeCoercion.scala`, `AnsiTypeCoercion.scala`, `CollationTypeCasts.scala`, and for testing `Collation*Suite.scala` files.
