Subject: Fixed bugs with annotation handling: An array initializer with more
 than 1 entry now no longer causes ArrayIndexOutOfBoundsException, the
 setWarning method on a single item in an array initializer on eclipse now
 generates the warning on just that node (like with errors), and the API of
 AnnotationValues has been updated to support setting errors/warning on any
 node.
