NPE in JSONWriter using Distributed Search w/Grouping
Hello -
I am doing some testing with a nightly build from 11/4/2011 and I regularly
encounter an NPE in the JSONWriter when performing a distributed search
with grouping on a single numeric field. The same searches non-disributed
to not encounter this issue. None of the individual shards log any sort of
error, however the server that is distributing the search logs the
following stack trace fairly regular and returns a 500 error:

Should I create a JIRA issue for this?

This does seems like a bug. I think you can open an issue. Can you
also add the exact query that causes this error in the issue?
