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

             Summary: Methods returning array may expose internal representation
                 Key: NUTCH-2812
                 URL: https://issues.apache.org/jira/browse/NUTCH-2812
             Project: Nutch
          Issue Type: Bug
    Affects Versions: 1.17
            Reporter: Lewis John McGibbney
            Assignee: Lewis John McGibbney
             Fix For: 1.18


Returning a reference to a mutable object value stored in one of the object's fields exposes the internal representation of the object.  If instances are accessed by untrusted code, and unchecked changes to the mutable object would compromise security or other important properties, you will need to do something different. Returning a new copy of the object is better approach in many situations.

For example org.apache.nutch.fetcher.FetchNode.getOutlinks() may expose internal representation by returning FetchNode.outlinks
