---------------------------------
[~caomanhdat] ...
RecoveryAfterSoftCommitTest has been failing roughly 50% of the time the past
few days - but only on master, and git bisect identifies your
[13a8356|https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=13a8356]
commit as the cause...
Here is an example of a seed from jenkins that reproduces reliably for me (and
fails a the same place everytime: {{RecoveryAfterSoftCommitTest.java:87}} ) ...

> URL: https://issues.apache.org/jira/browse/SOLR-12313
> Project: Solr
> Issue Type: Test
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Mark Miller
> Priority: Major
>
> This really should have some doc for why it would be used.
> I also think it causes BasicDistributedZkTest to take forever for sometimes
> and perhaps other tests?
> I think checking for uncommitted data is probably a race condition and should
> be removed.
> Checking index versions should follow the rules that replication does - if
> the slave is higher than the leader, it's in sync, being equal is not
> required. If it's expected for a test it should be a specific test that
> fails. This just introduces massive delays.
