--------------------------------------------

Hi David,

This should not be a problem as CandidateItemsStrategy is an interface and all methods of interface are public by default (http://docs.oracle.com/javase/specs/jls/se7/html/jls-6.html#jls-6.6.1).

Let me know if you still have trouble writing your own CandidateItemsStrategy.

> In order to implement a custom CandidateItemsStrategy, I'd like to extend {{AbstractCandidateItemsStrategy}}. This is not possible as the visibility modifier of {{doGetCandidateItems()}} is package default. Can it be extended to protected?
