Fix for bug 28773106

[Tomas-Kraus]

Here the issue is that The @xmlelement(nillable=false) doesn't work with String[]
i.e. nillable attribute is not honored by any array elements

So for the fix I have removed the check nav.isArray(type) from AbstractWrapperBeanGenerator.processXmlElement which sets nillable to true for all array type elements
