That exception means your index was written with a newer version of Lucene than the version you are using to open the IndexReader.
It looks like you used the unreleased (2.3 dev) version of Lucli from the Lucene trunk and then went back to an older Lucene JAR (maybe 2.2?) for accessing it? In general writing an index with a newer version of Lucene and then trying to access it using an older version of Lucene doesn't work (whereas the opposite does). I'm afraid you either have to switch to 2.3-dev for reading your index (but beware it could have sneaky bugs ...), or, rebuild your index with the 2.2 version of Lucene and use the 2.2 Lucli in the future.
