I think you misread the article.  No such bug/issue exists in Java.  The
listener example holds, but has nothing to do with private/protected.
That is an example of giving a reference to a datastructure and forgetting
you've done so.  Its not a memory leak.  A memory leak is when all
references to an allocated block of memory are lost and no mechanism
exists to reclaim it.
