While the question remains valid, I found there reason to my problem. Backing up I had saved Tomcat's descriptor file in my $SOLR_HOME and Solr was trying to read it as described in SolrCore Wiki<http://wiki.apache.org/solr/CoreAdmin> .
What saved me was remembering Chris's earlier remark<http://markmail.org/thread/3y4zqieyjqfi5vl3>. Thank you Chris!
