             Summary: Descriptors 2.0 module creates duplicate <alternatives/> entries (test case attached)
                 Key: SHRINKWRAP-398
                 URL: https://issues.jboss.org/browse/SHRINKWRAP-398
             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)

Linux ayaki.localdomain 3.3.0-4.fc16.x86_64 #1 SMP Tue Mar 20 18:05:40 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

         Attachments: ArquillianShrinkwrapDuplicateAlternatives.zip

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.
