> Key: LUCENE-5071
> URL: https://issues.apache.org/jira/browse/LUCENE-5071
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/store
> Affects Versions: 3.6.2, 4.3.1
> Environment: Linux kernel 3.2.0-48-generic
> jdk 1.6.0_43
> Reporter: Stephen Macke
> Labels: noob, patch
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> I think this actually affects 3.1.0 and up, but I was too lazy to type all
> those out and just included release versions for brevity.
> DirectIOLinuxIndexInput in 3.6.2 and NativeUnixIndexInput in 4.3.1 have in
> issue with the seek() method. If we seek() to the end of a file (can happen
> when merger is doing a clone()) whose length is a multiple of 512, then we
> will unnecessarily call refill(), which will throw an EOFException.
> Quick fix is to surround refill() with this condition:
> if (pos < length()) {
> refill();
> }
