Description

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

java.lang.ArrayIndexOutOfBoundsException: 0

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.
