             Summary: VariantListBuilderImpl build() don't work without add method
                 Key: CXF-7440
                 URL: https://issues.apache.org/jira/browse/CXF-7440
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 3.1.8
            Reporter: Michal Olsza
            Priority: Minor


Problem is within the class: {{org.apache.cxf.jaxrs.impl.VariantListBuilderImpl}}

After calling:
{code}
List<Variant> variants = Variant.mediaTypes(MediaType.APPLICATION_XML_TYPE, MediaType.APPLICATION_JSON_TYPE).build();
{code}

The {{variants}} list is empty. To get the expected result you need to call {{add()}} before {{build()}}. But [API states|http://docs.oracle.com/javaee/7/api/javax/ws/rs/core/Variant.VariantListBuilder.html#build--] that there should be no need for that. Even example from the API doesn't add the "German" variant.

{code}
List list = VariantListBuilder.newInstance()
         .languages(Locale.ENGLISH, Locale.FRENCH).encodings("zip", "identity").add()
         .languages(Locale.GERMAN).mediaTypes(MediaType.TEXT_PLAIN_TYPE)
         .build()
{code}
