Question: The last exam objective under "Java Streams" section in [1Z0-809 exam](http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=5001&get_params=p_exam_id:1Z0-809&p_org_id=1001&lang=US) (Java 8 exam) reads: 

> 
> Use of `merge()` and `flatMap()` methods of the Streams
>

There is no `merge()` method in `Stream` interface! 

There is a `merge(Object, Object, BiFunction)` method in `Map` but the exam objective clearly says "`merge()` and `flatMap()` methods of the Streams". Of course there is a `flatMap()` method in `Stream` interface. So what am I missing? Is the exam objective wrong? If its a mistake in the exam objective, how to contact Oracle for reporting this problem?

Answer: 
Same issue at Xcode 6.4. My workaround.

1. Rename Xcode 6.4 (Xcode64.app)
2. Install Xcode 7.1 (Xcode.app)
3. Build and archive in Xcode 6
4. Auto launch "Organizer" in Xcode 6 and **close**
5. Launch **Xcode 7 and Organizer**
6. Submit to App Store
Seems to be an issue with Xcode 6.4. Export the ipa and upload it using Application Loader.
