NullPointException when Faceting
I recently got this stack trace when trying to execute a facet based
query on my index. The error went away when I did an optimize but I
was surprised to see it at all. Can anyone shed some light on why
this may have happened?

I don't believe this is related to that bug as I don't set the facet
prefix. I have honestly never seen the issue before either and an
optimize fixed it. I can try to see if I can duplicate the issue
tomorrow, but since I've done the optimize I haven't seen it again.

I don't see how that could happen (and I've never seen it happen).
I recently fixed one NPE: https://issues.apache.org/jira/browse/SOLR-3150
Hopefully this isn't another!
