ClassCastException launching recent snapshot
Launching solr-4.0-20110705.223601-1.war, I get a class cast exception
org.apache.lucene.index.DirectoryReader cannot be cast to
org.apache.solr.search.SolrIndexReader with the following backtrace.
I'm launching solr-as-a-webapp via an embedded copy of tomcat 7. The
location of the index is set up via:
System.setProperty("solr.data.dir", solrDataDirectory);
Further, the sources in the corresponding -sources .jar doesn't seem
to have a cast to SolrIndexReader in it anywhere in SolrIndexSearcher.

I just checked the classpath. No strays.
You can't 'use the example solr installation' when downloading the war
artifact from the snapshot repo.
You might ask me: what happens if I just drop that war into a plain
tomcat? And I plan to try that.

I built a fresh set of snapshots myself, I carefully cleaned my
project, and everything is happy. So this goes down in the department
of pirate error.

Then I would guess that you have other (older) jars in your classpath
somewhere. Does the example Solr installation work?
