Unable to detect changes not default schema

I am using Oracle DB for testing.
Also, the application user and the schema management user are different.

Watching at changes.changesList in the code below, it's null.

```
OracleDataSource ods = new OracleDataSource();
ods.setURL(...);
ods.setUser(...);
ods.setPassword(...);

Changes changes = new Changes(ods);
changes.setStartPointNow();

makeChangesInTheData();

changes.setEndPointNow();
```

Changes targets the default schema for change detection, can it target another schema?
