#198 too many foreign keys on oracle

[Schoemer, Joerg]

The Oracle JDBC driver reports in call to
getExportedKeys() keys of other schemas even if a
schema or catalog has to be filtered.

e.g.

MY.ARTICLE --+--+
| |
| +-< MY.ORDER_ITEMS
|
+----< OTHER.ORDER_ITEMS

the effect is, that the class article has two sets of
orderItems with the same name

<code>
class Article {
...

Set orderItems;

Set orderItems;
~~~~~~~~~~~~~~~
...
}
</code>

I've patched the MiddlegenPopulator.java as attached

Best regards
Joerg
