Uwe Schindler resolved LUCENE-5678.
-----------------------------------
Resolution: Fixed
Committed to trunk.
We might backport this to 4.x, once we removed deprecated seek() in
IndexOutput. We can discuss this later, once this simplified/standardized code
has proven to be as fast and stable.
> Investigate to use FileoutputStream instead of RandomAccessFile in
> FSIndexOutput

> We no longer allow seeking in IndexOutput, so there is no need to use
> RandomAccessFile. We can change this with a < 1 KiB patch.
> Further improvements would be to merge this with OutputStreamIndexOutput, so
> we get many simplifications.
> There is also no reason anymore to separate DataOutput from IndexOutput. The
> only additional thing is IndexOutput#getFilePointer(), which is handled by
> an internal counter (does not use getFilePointer of the underlying RAF) and
> checksums.
