> If you create an index in 2.3.x (I used demo's IndexFiles) and then try to read it in 4.0.x (I used CheckIndex), you hit a confusing exception like this:
> {noformat}
> java.io.IOException: read past EOF
> at org.apache.lucene.store.BufferedIndexInput.refill(BufferedIndexInput.java:154)
> at org.apache.lucene.store.BufferedIndexInput.readByte(BufferedIndexInput.java:39)

> {noformat}
> I think instead we should throw an IndexTooOldException or something like that?
