Michael McCandless commented on LUCENE-5934:
--------------------------------------------

Can we move the codec check:

{noformat}
      if ((si.getCodec() instanceof Lucene3xCodec) == false) {
{noformat}

up into SIS.write, just before:

{noformat}
          if (!segmentWasUpgraded(directory, si)) {
{noformat}

?

This way if something like this tries to happen again in 4.x, at least we don't 
corrupt-on-kiss and instead just throw the exception and rollback the commit.

> 4.10 broke backwards compatibility for 4.0 indexes
