Stefan Moises commented on SOLR-2504:
-------------------------------------

I am the initial reporter of this bug in the mailing list and currently we are using a nightly
build of Solr (apache-solr-4.0-2011-03-16_08-16-50.tar) and still get the error, so I don't
think it has been fixed yet, unless those changes you've mentioned have been at a later date
or in another branch - here are my line numbers from that nighly build:
