I had assumed that, since it didn't have the leading "2" as in VARCHAR2 it was one of those peculiar Oracle types tagged as "do not use!" like, well, VARCHAR. And something that didn't help is that SQL Developer doesn't allow such type in the "Add column" dialog.
This is what happens when you code in more DBMS than you're able to learn xD
