RAMDirectory reports incorrect EOF on seek
------------------------------------------

                 Key: LUCENE-1196
                 URL: https://issues.apache.org/jira/browse/LUCENE-1196
             Project: Lucene - Java
          Issue Type: Bug
          Components: Store
    Affects Versions: 2.3.1, 2.3, 2.2, 2.1, 2.0.0, 1.9, 2.4, 2.9, 3.0
            Reporter: Michael McCandless
            Assignee: Michael McCandless
            Priority: Minor
             Fix For: 2.4


If you create a file whose length is a multiple of 1024 (BUFFER_SIZE),
and then try to seek to the very end of the file, you hit
EOFException.

But this is actually "legal" as long as you don't try to read any
bytes at that point.

I'm hitting this (rarely) with the bulk-merging logic for term vectors
(LUCENE-1120), which can seek to the very end of the file but not read
any bytes if conditions are right.
