Thanks for backporting [[email protected]]!
Hmm, now I'm hitting this test failure on 4.9.x:

I dug just a bit... looks like we are passing len=0 to
MockReaderWrapper.read(char[], int, int), which it can't handle (it calls
{{realLen = TestUtil.nextInt(random, 1, len);}}) ... I'm not sure why we don't
hit this on 4.x/trunk...

> Key: LUCENE-5400
> URL: https://issues.apache.org/jira/browse/LUCENE-5400
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 4.5
> Reporter: Chris Geeringh
> Assignee: Steve Rowe
> Fix For: 4.10, 5.0, 4.9.1
>
>
> This is a pretty nasty bug, and causes the cluster to stop accepting updates.
> I'm not sure how to consistently reproduce it but I have done so numerous
> times. Switching to a whitespace tokenizer improved indexing speed, and I
> never got the issue again.
> I'm running a 4.6 Snapshot - I had issues with deadlocks with numerous
> versions of Solr, and have finally narrowed down the problem to this code,
> which affects many/all(?) versions of Solr.
> When the thread hits this issue it uses 100% CPU, restarting the node which
> has the error allows indexing to continue until hit again. Here is thread
> dump:
