Check the dates for the Solr/Lucene jars - they might be an early snapshot
before the index format stabilized.
Or, maybe that Mahout sub-project had a copy of some old Lucene data.
Keeping old Lucene data around as opposed to reindexing is a rather bad
idea.

Try this
http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/index/IndexUpgrader.html
I'm wondering why a newly created index, created with the latest release
of solr 4.0 is "too old". Am I missing some config options? In
particular as it states:
This version of Lucene only supports indexes created with release 1.9
and later.
which is way back. Either it's a bug or some configuration or
installation went wrong.
