Back-compat break with non-ascii field names
--------------------------------------------
Key: LUCENE-1623
URL: https://issues.apache.org/jira/browse/LUCENE-1623
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 2.4.1, 2.4
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 2.9
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.
