[jira] [Comment Edited] (CALCITE-455) User-defined functions should
be able to use custom java arguments

{{MyUnWrapFunction}} with {{Object}} argument works properly.
I guess the problem might be somewhere in [OptiqCatalogReader.toSql|https://github.com/apache/calcite/tree/8e480759fc25d7a1e10f7f20f9eddc7556beded8/core/src/main/java/net/hydromatic/optiq/prepare/OptiqCatalogReader.java#L248]
