Description

I'm guessing this is a test bug, but the seed doesn't reproduce for me (tried on the same Linux machine it occurred on and on OS X):

Line 547 of ShardSplitTest.java is:

      idVsVersion.put(document.getFieldValue("id").toString(), document.getFieldValue("_version_").toString());

Skimming the code, it's not obvious what could be null.
