> 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: 1.9, 2.0.0, 2.1, 2.2, 2.3, 2.3.1, 2.4, 2.9, 3.0
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 2.4
> 
> Attachments: LUCENE-1196.patch
> 
> 
> 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.
