Steps to Reproduce:

Create an annotation type

@Target({ElementType.TYPE}) public @interface MyAnnotation { String[] value(); }

and add it to a type with null element

@MyAnnotation({null}) public class C { }

In this case, method validateNamedValue gets parameter value=null and fails at line

String stringValue = value.toString();

Comment to method IMemberValuePair.getValue() says that it may return null.
