---------------------------------------

             Summary: ClassUtil fails with ArrayIndexOutOfBoundsException if WildcardType.getUpperBound() returns empty array
                 Key: OWB-907
                 URL: https://issues.apache.org/jira/browse/OWB-907
             Project: OpenWebBeans
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.8
            Reporter: Christian Kaltepoth


If WildcardType.getUpperBounds() returns an empty error, OWB throws the following exception:

java.lang.ArrayIndexOutOfBoundsException: 0
	at org.apache.webbeans.util.ClassUtil.checkRequiredTypeIsWildCard(ClassUtil.java:875)
	at org.apache.webbeans.util.ClassUtil.isAssignableForParametrizedCheckArguments(ClassUtil.java:798)
	at org.apache.webbeans.util.ClassUtil.isAssignableForParametrized(ClassUtil.java:768)
	at org.apache.webbeans.util.ClassUtil.isAssignable(ClassUtil.java:552)
	at org.apache.webbeans.container.InjectionResolver.implResolveByType(InjectionResolver.java:501)
	at org.apache.webbeans.container.InjectionResolver.implResolveByType(InjectionResolver.java:411)
	at org.apache.webbeans.container.BeanManagerImpl.getBeans(BeanManagerImpl.java:678)
	at org.apache.webbeans.container.InjectableBeanManager.getBeans(InjectableBeanManager.java:105)

>From my understanding of the WildcardType javadocs an empty array is a valid result of invoking this method and actually means that Object is the upper bound.
