> If a field name contains non-ascii characters in a 2.3.x index, then
> on upgrade to 2.4.x unexpected problems are hit.  It's possible to hit
> a "read past EOF" IOException; it's also possible to not hit an
> exception but get an incorrect field name.
> This was caused by LUCENE-510, because the FieldInfos (*.fnm) file is
> not properly versioned.
> Spinoff from http://www.nabble.com/Read-past-EOF-td23276171.html
