-----------------------------------------
Tim, the change to the LIR state to be kept as map is not back-compatible. For
example, I saw the following error upon upgrading a cluster (to trunk) (which
had some LIR state written down in ZK already). But looking at the code, the
same exception can happen on upgrading to latest lucene_solr_4_10 branch too.
{code}
