>             Project: ShrinkWrap
>          Issue Type: Bug
>          Components: ext-descriptors
>    Affects Versions: 1.0.0
>         Environment: java version "1.7.0_01"
> Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
> Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)

> Using: org.jboss.shrinkwrap.descriptors:shrinkwrap-descriptors-impl-javaee:jar:2.0.0-alpha-2
> The attached test case produces an invalid beans.xml with a duplicate <alternatives/> entry with the code:
>         BeansDescriptor beansXml = Descriptors.importAs(BeansDescriptor.class)
>                 .from(new File("src/main/webapp/WEB-INF/beans.xml"))
>                 .getOrCreateAlternatives();
> 'getOrCreate' is in fact always creating an alternatives entry.
> Also: Since there can only ever be one <alternatives/> block, it's not clear what the difference between getOrCreateAlternatives() and createAlternatives() is. Is the latter supposed to *replace* any existing block?
> The API for managing alternatives is in Descriptors 2.0 is IMO difficult to use and understand. Issues with examples pending.
