Enabling Java

We are unable to enable Java in the Oracle Autonomous Database. The documentation says to do this, but it's not working

```PLSQL
BEGIN
   DBMS_CLOUD_ADMIN.ENABLE_FEATURE(
       feature_name => 'JAVAVM' );
END;
```
How would we do this?

> Edit: I just saw that someone else had the same issue last year. Is there a way to resolve this?
