My guess is that the headerKey attribute is always evaluated as a string. Since you're using a List<Integer>, even if the string representations are the same, it won't match (see [1]).
That's probably worth an "improvement" JIRA if there isn't one in there already, although I haven't looked at it to see how easy/hard the change would be.
