Since the default value for the keyColumn field is "", wouldn't you want to filter that out? Perhaps something like:
...map(Column::keyColumn).filter(x -> x != null && !x.equals(""))

You were right, filtering out the default value is important here, I have added that.
Why are you also checking x for being not null, that case can not come up if I'm not mistaken.

Yes, that's my bad. Forgot that null isn't an allowable value for annotations. It's been a while since I've written a custom annotation processor :)

Also: Added documentation for the new behavior. Made the value of the column annotation optional by providing a default. Original pull request: #83.

This adds the functionality requested in DATAJDBC-218, so you can now customize the key column name for List and Map collections inside the @column annotation.
I have also added a test case to demonstrate the behavior.
